visjs-network

A dynamic, browser-based network visualization library. A network-visualization focused fork of the visualization library vis.js

visjs-network is designed to be easy to use, handle dynamic data, and enable data manipulation. The library consists of the following components:

Network. Display a network (force directed graph) with nodes and edges.
DataSet and DataView. A flexible key/value based data set. Add, update, and remove items. Subscribe on changes in the data set. A DataSet can filter and order items, and convert fields of items.
DataView. A filtered and/or formatted view on a DataSet.

Install

Install via yarn:

yarn add visjs-network

Install via npm:

npm install visjs-network

Install via bower:

bower install visjs-network

Or download the library from the github project: https://github.com/visjs-community/visjs-network.git.

Load

To use a component, include the javascript and css files of vis in your web page:

<!DOCTYPE HTML>
<html>
<head>
  <script src="webroot/vis/dist/vis.js"></script>
  <link href="webroot/vis/dist/vis.css" rel="stylesheet" type="text/css" />
</head>
<body>
  <script type="text/javascript">
    // ... load a visualization
  </script>
</body>
</html>

or load vis.js using require.js. Note that vis.css must be loaded too.

require.config({
  paths: {
    vis: 'path/to/vis/dist'
  }
})
require(['vis'], function(math) {
  // ... load a visualization
})

Examples

yarn examples

Run the yarn examples command to explore the examples locally. This command launches a local server, opens a browser window, and navigates that browser window to the index page for the top-level examples directory.

Examples can be found in the examples/ directory of the project.

Build

To build the library from source, clone the project from github

git clone git://github.com/visjs-community/visjs-network.git

The source code uses the module style of node (require and module.exports) to organize dependencies. To install all dependencies and build the library, run yarn or npm install in the root of the project.

cd vis
yarn

Then, the project can be built by running:

yarn build

To automatically rebuild on changes in the source files, once can use

yarn watch

This will both build and minify the library on changes. Minifying is relatively slow, so when only the non-minified library is needed, one can use the watch-dev script instead:

yarn watch-dev

Custom builds

The folder dist contains bundled versions of vis.js for direct use in the browser. These bundles contain all the visualizations and include external dependencies such as hammer.js and moment.js.

The source code of vis.js consists of commonjs modules, which makes it possible to create custom bundles using tools like Browserify or Webpack. This can be useful when bundling vis.js as part of your own browserified web application.

Note that hammer.js version 2 is required as of v4.

Prerequisites

Before you can do a custom build:

Install node.js and npm on your system: https://nodejs.org/
Install yarn on your system: https://yarnpkg.com/en/
Install the following modules globally using yarn: browserify, babelify, and uglify-js:
```
yarn global add browserify babelify uglify-js
```

Download or clone the vis.js project:

git clone https://github.com/visjs-community/visjs-network.git

Install the dependencies of vis.js by running yarn or npm install in the root of the project:
```
cd vis
npm install
```

Examples of custom builds

Example 1: Exclude external libraries

The default bundle vis.js is standalone and includes external dependencies such as hammer.js and moment.js. When these libraries are already loaded by the application, vis.js does not need to include these dependencies itself too. To build a custom bundle of vis.js excluding moment.js and hammer.js, run browserify in the root of the project:

browserify index.js -t [ babelify --presets [env] ] -o dist/vis-custom.js -s vis -x moment -x hammerjs

This will generate a custom bundle vis-custom.js, which exposes the namespace vis, and has moment.js and hammer.js excluded. The generated bundle can be minified with uglifyjs:

uglifyjs dist/vis-custom.js -o dist/vis-custom.min.js

The custom bundle can now be loaded as:

<!DOCTYPE HTML>
<html>
<head>
  <!-- load external dependencies -->
  <script src="http://cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script>
  <script src="http://cdnjs.cloudflare.com/ajax/libs/hammer.js/2.0.8/hammer.min.js"></script>

  <!-- load vis.js -->
  <script src="dist/vis-custom.min.js"></script>
  <link href="dist/vis.min.css" rel="stylesheet" type="text/css" />
</head>
<body>
  ...
</body>
</html>

Test

To test the library, install the project dependencies once:

yarn

Then run the tests:

yarn test
