Visualizing network graphs using JavaScript

I am in search of a JavaScript network visualization graph (not a chart) that can handle JSON input effectively. I have tried using the JIT infovis toolkit, RGraph, and space tree to display multiple levels in the graph. However, I have encountered issues such as nodes collapsing with large datasets in RGraph, and edges merging with nodes in RGraph. Space tree also presents challenges where children with multiple parents are spaced too far apart, making it unstable for handling large volumes of data. I am struggling to find graphs that work well with the JSON input format used by infovis. Any suggestions on alternative solutions to improve the performance of infovis space tree and RGraph would be greatly appreciated. Thank you in advance.

Answer №1

In my opinion, my top choice is vis.js due to the following reasons:

  • The generated network is flexible and adjusts automatically when the user reshapes it.
  • It includes convenient UI features like zoom-in and zoom-out options.
  • The network allows for extensive customization in terms of edge colors, width, and more.
  • No need to specify X,Y coordinates for nodes when defining them (which some other libraries require).
  • Additionally, it is incredibly user-friendly as showcased below:

Here's how you can use it:

// create an array with nodes
var nodes = new vis.DataSet([
{id: 1, label: 'Node 1'},
{id: 2, label: 'Node 2'},
{id: 3, label: 'Node 3'},
{id: 4, label: 'Node 4'},
{id: 5, label: 'Node 5'}
]);

// create an array with edges
var edges = new vis.DataSet([
{from: 1, to: 3, width: 1},
{from: 1, to: 2, width: 6},
{from: 2, to: 4, width: 1},
{from: 2, to: 5, width: 3},
{from: 2, to: 3, width: 1},
]);

// create a network
var container = document.getElementById('mynetwork');
var data = {
nodes: nodes,
edges: edges
};
var options = {};
var network = new vis.Network(container, data, options);

Take a look at D3, which is a powerful JavaScript library designed for document manipulation based on data, and also explore sigma.js, an open-source lightweight JavaScript library specifically crafted for drawing graphs using the HTML canvas element.

Answer №3

From my understanding, there are various open-source JavaScript projects available for graph visualization.

  1. JIT, which is currently in use.
  2. arborjs
  3. protovis created by Stanford University. It appears promising, but it is no longer actively maintained.

I personally have not incorporated them into any of my projects, so feel free to explore them on your own.

Answer №4

Take a look at netjsongraph.js, an easy-to-use javascript library powered by D3 and built to support the NetJSON format, specifically tailored for networking software.

Check out the live demonstration of the netjsongraph demo example.

I trust this will be beneficial for you.

If you're looking for an interactive HTML5 charts library, be sure to check out Data Visualization Software Lab:

This innovative SDK allows you to create a variety of charts including time-based charts, network charts, and pie charts. Plus, they have Geo charts, facet charts, and XML Charts coming soon.

  • Time based charts
  • Network charts
  • Pie charts
  • Coming soon are Geo charts, facet charts and XML Charts

All graphs are pure HTML5 with no dependencies on other libraries, making integration with any JS framework easy (such as jQuery). The SDK uses Canvas for rendering and offers full multi-touch support for data navigation, interaction, and exploration.

Check out this example of a network chart:

The charts also come with extensive API and settings options, giving you control over every aspect of your visualization.
