A web component to represent a graph data structure in a 3-dimensional space using a force-directed iterative layout. And check out the React bindings.
Which type of control to use to control the camera. Choice between trackballorbit or fly. Can also be used to apply incremental updates. Node object accessor function, attribute or a numeric constant for the node numeric value affects sphere volume. Node object accessor function or attribute for name shown in label. Supports plain text or HTML content.
Node object accessor function fn node or attribute e. Only affects nodes without a color attribute. Higher values yield smoother spheres. Node object accessor function or attribute for generating a custom 3d object to render as graph nodes. Should return an instance of ThreeJS Object3d. If a falsy value is returned, the default 3d object type will be used instead for that node. Node object accessor function, attribute or a boolean value for whether to replace the default node when using a custom nodeThreeObject false or to extend it true.
Link object accessor function or attribute for name shown in label. Link object accessor function, attribute or a boolean constant for whether to display the link line. A value of false maintains the link force without rendering it. Link object accessor function fn link or attribute e. Only affects links without a color attribute. Link object accessor function, attribute or a numeric constant for the link line width.
A value of zero will render a ThreeJS Line whose width is constant 1px regardless of distance. Values are rounded to the nearest decimal for indexing purposes. Higher values yield smoother cylinders. Applicable only to links with positive width. Link object accessor function, attribute or a numeric constant for the curvature radius of the link line.
Curved lines are represented as 3D bezier curves, and any numeric value is accepted. A value of 0 renders a straight line. For self-referencing links source equal to target the curve is represented as a loop around the node, with length proportional to the curvature value. Lines are curved clockwise for positive values, and counter-clockwise for negative values. Note that rendering curved lines is purely a visual effect and does not affect the behavior of the underlying forces.
Link object accessor function, attribute or a numeric constant for the rotation along the line axis to apply to the curve.
Has no effect on straight lines. At 0 rotation, the curve is oriented in the direction of the intersection with the XY plane. The rotation angle in radians will rotate the curved line clockwise around the "start-to-end" axis from this reference orientation. Link object accessor function or attribute for specifying a custom material to style the graph links with.
Should return an instance of ThreeJS Material. If a falsy value is returned, the default material will be used instead for that link. Link object accessor function or attribute for generating a custom 3d object to render as graph links. If a falsy value is returned, the default 3d object type will be used instead for that link.If you enjoy this library, please consider supporting me for developing and maintaining it. Here a live playground page where you can interactively config your own graph, and generate a ready to use configuration!
You can also load different datasets and configurations via URL query parameter, here are the links:. Do you want to visualize your own data set on the live sandbox?
Just submit a PR! Full documentation here. Note that react and d3 are peer-dependenciesthis means that the responsibility to install them is delegated to the client. This will give you more flexibility on what versions of d3 and react you want to consume, you just need to make sure that you are compliant with the range of versions that react-d3-graph is compatible with.
If you install react-d3-graph without first installing d3 and react you might see the following warnings:. You must install peer dependencies yourself. Graph component is the main component for react-d3-graph components, its interface allows its user to build the graph once the user provides the data, configuration optional and callback interactions also optional.
The code for the live example can be consulted here. If you are more a hands on person, just submit a pull request. To run react-d3-graph in development mode you just need to run npm run dev and the interactive sandbox will reload with the changes to the library code, that way you can test your changes not only through unit test but also through a real life example. It's that simple. The development workflow usually should follow the steps:.

Report a vulnerability.At Smartcar, we wanted to create a graph that would showcase our users' API usage over time and give them insights into the requests they've made, so we confronted this issue head-on.
At Smartcar, we wrap a library that can handle this, like moment. Alright, let's get started by creating the most fundamental part of the graph — the scales and axes.Data Visualization with l42mephadow.pw - Full Tutorial Course
Now that we've set up these elements for our line chart, we'll also need to use D3 to specify their place on the DOM. Adding the axes and line to our graph will look something like this:.
Now we're ready to put it all together. Let's attach our axes and line to their designated DOM elements. Finally, let's write the method we mentioned a bit earlier: d3Utils. In the previous two sections, we set up a basic time series line chart and rendered it in our React component.
Now, let's enhance the dynamic capabilities of our graph and enable it to update when new data comes in. In this function, we'll watch for changes in our data and trigger readjustments when necessary.
Now that we have the React side of things ready to go, let's write our d3Utils. When new data comes in, we'll mainly want to check for two things:. Finally, we can write our handleNewData method with the functions above. We'll have to re-draw the elements of our graph to render the changes on our line chart. Now your time series line chart can dynamically update to showcase the most recent data available.
The final optimization we'll detail today is how to make your graph responsive across browsers. Because the scale of our x-axis is determined by the width of the graph, we'll need to adjust this accordingly for different screen sizes. We'll need to add an event listener to our component in order to detect changes in screen size and remove it when the component unmounts as well as write a method to set the new width.
After all these changes have been made, our component will look something like this:. And last but not least, let's write d3Utils. In order to get the current width of our line chart, we'll simply find the SVG on the DOM, measure its width, and adjust the range of our x-scale accordingly.
And there you go! Now you have a dynamic, responsive time series line chart built in React and D3. At Smartcar, we've added a few extra bells and whistles to our usage graph to spice it up a bit.

Now I wonder how to build a svg graphic like the d3 force layout which involves physics and user interaction. Since D3 and React haven't decreased in popularity the last three years, I figured a more concrete answer might help someone here who wants to make a D3 force layout in React. Creating a D3 graph can be exactly the same as for any other D3 graph. But you can also use React to replace D3's enter, update and exit functions. So React takes care of rendering the lines, circles and svg.
This could be helpfull when a user should be able to interact a lot with the graph.
Where it would be possible for a user to add, delete, edit and do a bunch of other stuff to the nodes and links of the graph. There are 3 components in the example below.
The App component holds the app's state. In particular the 2 standard arrays with node and link data that should be passed to D3's d3. Then there's one component for the links and one component for the nodes. You can use React to do anything you want with the lines and circles.
You could use React's onClickfor example. The functions enterNode selection and enterLink selection render the lines and circles. These functions are called from within the Node and Link components.
Creating Graphs as React Components with D3.js
These components take the nodes' and links' data as prop before they pass it to these enter functions. The functions updateNode selection and updateLink selection update the nodes' and links' positions. They are called from D3's tick function. It's only possible to add nodes in the example below. But I hope it shows how to make the force layout more interactive using React. There is a b. Everyone who implements force-layouts in React notices a minor performance loss.
For complex charts beyond nodes this becomes much more severe. Note: There is an open issue on react-motion for applying forces which would otherwise be a good react solution to this but its gone silent. My question is to vincent. The code compiles perfectly but when i run it the background gets drawn with the blue color but the graph actually renders as 4 dots on the top left corner.
That is all gets drawn. I have tried may approaches but always seem to be getting the same results just 4 dots on the top left corner. Would appreciate it if you could let me know if you had this problem.

Nodes are just characters that appear in the movie. They have a name and a group that they're associated with. Then, links correspond to when two characters actually appear in a scene together. There's a source value and a target value, which correspond to the actual character.

Then, the value here for a link actually corresponds to when two characters appear in a scene together. Here, our React component's going to be called forceLayout, and it's going to extend from the React. Our render method is just going to initially grab the width and the height off of the props that are passed into it. We'll also make a style object that's just going to hold on to the width and height information and also include a border, which is just an off-black value.
What render is going to return is actually a single DOM node that's a div, and it's going to have that style object on it. It's actually going to contain a ref called mountPoint, which D3 is going to use to render into later on. This component is a container component, which means that this div is going to contain all of the rendering done by D3, which we'll manage in the componentDidMount lifecycle method. We'll just go and initialize the force layout component with the width and the height prop, and we'll actually use document.
If we go and check this out in the output, we can see that our container component was rendered properly, so we're good to go to jump into the componentDidMount lifecycle method. More importantly, we can use D3 to hook into that mount point to actually render. We'll start out by grabbing width and height, once again, off of props.
Then we're going to use the D3 force layout to actually drive the algorithmic behavior of our visualization. Just to give you an idea of what the force layout module actually gives us, I'll go ahead and log out the keys here. We can see that the force layout module really is just a collection of configuration options, like link distance or friction.
We can also call things like drag, which will implement that node drag behavior. We can even listen to events using the on method, as well, like onTick. Now that we know that this layout can be configured, we'll go ahead and copy the properties from that example from before like charge and link distance.
We'll also go ahead and add the size attribute for it, which will be based off of the props of our component. Finally, we'll include the nodes and the links from our data variable. If we go and log it out to the console, we can see that each object here just has a name and a group.
How to create a dynamic and responsive time series graph with D3 and React
Links are similar in that they have the source value, a target value, and then an actual value. We can actually bootstrap our force layout by calling force. What's important is that we specify some kind of handler for the tick event.
What the tick event allows us to do is hook into whenever the layout wants to update itself. If I go and log out the current time whenever the tick event is called and we can see it out here in the console, you can see that it's called almost 60 times a second, which is the ideal frame rate for our animation here inside of our visualization.
What's even more important to realize is that our nodes and our links are also changing over time. Here, I'll go and log out just the first node in our entry of nodes.Mock HTTP requests with tweak chrome extension. Reproduce edge cases in your UI.

Note about performance Some of the properties have a major performance impact when toggled while rendering graphs of medium or large dimensions hundreds or thousand of elements.
This means that this properties have a higher level of granularity. These properties can be defined in the graph payload at a node level. Then you just need to make sure that you pass this function in the config in config.
Graph component is the main component for react-d3-graph components, its interface allows its user to build the graph once the user provides the data, configuration optional and callback interactions also optional. The code for the live example can be consulted here. Obtain a set of properties which will be used to perform the focus and zoom animation if required.
In case there's not a focus and zoom animation in progress, it should reset the transition duration to zero and clear transformation styles. Sets d3 tick function and configures other d3 stuff such as forces and drag events. Whenever called binds Graph component state with d3.
Handles d3 'drag' event. The tick function simply calls React set state in order to update component and render nodes along time as d3 calculates new node positioning. Configures zoom upon graph with default or user provided values. NOTE: in order for users to be able to double click on nodes, we are disabling the native dblclick. Collapses the nodes, then checks if the click is doubled and calls the callback passed to the component.
Calls d3 simulation. This method resets all nodes fixed positions by deleting the properties fx fixed x and fy fixed y. Following this, a simulation is triggered in order to force nodes to go back to their original positions or at least new positions according to the d3 force parameters.
Builds graph defs for now markers, but we could also have gradients for instance. NOTE: defs are static svg graphical objects, thus we only need to render them once, the result is cached on the 1st call and from there we simply return the cached jsx. Method that actually is exported an consumed by Graph component in order to build all Nodes and Link components.
Offers a series of methods that isolate the way graph elements are built nodes and links mainly. Get the correct node opacity in order to properly make decisions based on context such as currently highlighted node. Offers a series of methods that isolate logic of Graph component and also from Graph rendering methods.
Type: Object. Create d3 forceSimulation to be applied on the graph. Receives a matrix of the graph with the links source and target as concrete node instances and it transforms it in a lightweight matrix containing only links with source and target being strings representative of some node id and the respective link value if non existent will default to 1.
Method that initialize graph nodes provided by rd3g consumer and adds additional default mandatory properties that are optional for the user. Also it generates an index mapping, this maps nodes ids the their index in the array of nodes.
This is needed because d3 callbacks such as node click and link click return the index of the node. If d3Link with given index exists already that same d3Link is returned. Some integrity validations on links and nodes structure. If some validation fails the function will throw an error. Returns the transformation to apply in order to center the graph on the selected node.
This function extracts an id from a link. Why this function?React has been the choice for many developers in last year and will continue to grow in coming years.
You would need to put lots of additional effort in order to make a d3 chart reusable across your application. We will look into other advantages, but lets see how we can actually integrate React and D3. So most of the time we will use React to update the DOM however will be fully utilizing the Math functions provided by D3. In short, we will not be able to use d3. Note: In very few scenarios we will still let D3 update the DOM since converting those functions in React could be overkilling.
Here are some facts, we will be covering them in our demo and example. As described earlier, the charts could be reused across the application without any additional coding. Updating the charts using React also will be very simple. We need to define the props and state properly in React to get the full benefit of this.
We can also adapt Flux Architecture We will talk about this in a future post to extend the capabilities. This is another very important functionality. Using React we can create responsive charts without even having to add any custom code for every chart.
Once you integrate React and D3 you would almost create a library of charts which can be easily shared and modified. You unit testing will also become easy. You can relate this to the Procedural vs Object Oriented Programming. D3 can be integrated with React by another way Like any other library. However this is not an efficient of way of integrating them together.
Lets look at few Disadvantages of Integrating React and D3 below:. D3 transitions functions cannot be used. You may try using React Animation however it will be a separate topic to discuss in future posts. Otherwise the only option is to use the core d3 library to perform the animation.
We will create a small dashboard using React and D3. You can find the live demo here.
