# vis.js (deprecated!)



:exclamation: **This project is not maintained anymore! (See [Issue #4259](http://github.com/almende/vis/issues/4259#issue-412107497) for details)**
**We welcome you to use the libraries from the [visjs community](https://www.github.com/visjs) from now on.**



---



Vis.js is a dynamic, browser based visualization library.

The library is designed to be easy to use, handle large amounts

of dynamic data, and enable manipulation of the data.

The library consists of the following components:



- 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.

- Graph2d. Plot data on a timeline with lines or barcharts.

- Graph3d. Display data in a three dimensional graph.

- Network. Display a network (force directed graph) with nodes and edges.

- Timeline. Display different types of data on a timeline.



The vis.js library was initially developed by [Almende B.V](http://almende.com).



## Install



Install via npm:



```sh

npm install vis

```



Install via bower:



```sh

bower install vis

```



Link via cdnjs: https://cdnjs.com/libraries/vis



Or download the library from the github project:

[https://github.com/almende/vis.git](https://github.com/almende/vis.git).



## Load



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



```html



  

  



  

    // ... load a visualization

  



```



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



```js

require.config({

  paths: {

    vis: 'path/to/vis/dist',

  }

});

require(['vis'], function (math) {

  // ... load a visualization

});

```



A timeline can be instantiated as:



```js

var timeline = new vis.Timeline(container, data, options);

```



Where `container` is an HTML element, `data` is an Array with data or a DataSet,

and `options` is an optional object with configuration options for the

component.



## Example



A basic example on loading a Timeline is shown below. More examples can be

found in the [examples directory](https://github.com/almende/vis/tree/master/examples)

of the project.



```html



  Timeline basic demo

  

  



  

    body, html {

      font-family: sans-serif;

    }

  






  var container = document.getElementById('visualization');

  var data = [

    {id: 1, content: 'item 1', start: '2013-04-20'},

    {id: 2, content: 'item 2', start: '2013-04-14'},

    {id: 3, content: 'item 3', start: '2013-04-18'},

    {id: 4, content: 'item 4', start: '2013-04-16', end: '2013-04-19'},

    {id: 5, content: 'item 5', start: '2013-04-25'},

    {id: 6, content: 'item 6', start: '2013-04-27'}

  ];

  var options = {};

  var timeline = new vis.Timeline(container, data, options);



```



## Build



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



```sh

git clone git://github.com/almende/vis.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 `npm install` in the root of the project.



```sh

cd vis

npm install

```



Then, the project can be build running:



```sh

npm run build

```



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



```sh

npm run 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:



```sh

npm run 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](http://browserify.org/) or [Webpack](http://webpack.github.io/). This can be bundling just one visualization like the Timeline, or 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 build:



- Install *node.js* and *npm* on your system: https://nodejs.org/

- Install the following modules using npm: `browserify`, `babelify`, and `uglify-js`:



```sh

[sudo] npm install -g browserify babelify uglify-js

```



- Download or clone the vis.js project:



```sh

git clone https://github.com/almende/vis.git

```



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



```sh

cd vis

npm install

```



### Examples of custom builds



#### Example 1: Bundle only a single visualization type



For example, to create a bundle with just the Timeline and DataSet, create an index file named **custom.js** in the root of the project, containing:



```js

exports.DataSet = require('./lib/DataSet');

exports.Timeline = require('./lib/timeline/Timeline');

```



Then create a custom bundle using browserify, like:



```sh

browserify custom.js -t [ babelify --presets [es2015] ] -o dist/vis-custom.js -s vis

```



This will generate a custom bundle *vis-custom.js*, which exposes the namespace `vis` containing only `DataSet` and `Timeline`. The generated bundle can be minified using uglifyjs:



```sh

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

```



The custom bundle can now be loaded like:



```html



  

  



  ...



```



#### Example 2: 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:



```sh

browserify index.js -t [ babelify --presets [es2015] ] -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:



```sh

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

```



The custom bundle can now be loaded as:



```html



  

  

  



  

  

  



  ...



```



#### Example 3: Bundle vis.js as part of your (commonjs) application



When writing a web application with commonjs modules, vis.js can be packaged automatically into the application. Create a file **app.js** containing:



```js

var moment = require('moment');

var DataSet = require('vis/lib/DataSet');

var Timeline = require('vis/lib/timeline/Timeline');



var container = document.getElementById('visualization');

var data = new DataSet([

  {id: 1, content: 'item 1', start: moment('2013-04-20')},

  {id: 2, content: 'item 2', start: moment('2013-04-14')},

  {id: 3, content: 'item 3', start: moment('2013-04-18')},

  {id: 4, content: 'item 4', start: moment('2013-04-16'), end: moment('2013-04-19')},

  {id: 5, content: 'item 5', start: moment('2013-04-25')},

  {id: 6, content: 'item 6', start: moment('2013-04-27')}

]);

var options = {};

var timeline = new Timeline(container, data, options);

```



The application can be bundled and minified:



```sh

browserify app.js -o dist/app-bundle.js -t babelify

uglifyjs dist/app-bundle.js -o dist/app-bundle.min.js

```



And loaded into a webpage:



```html



  



  


  



```



#### Example 4: Integrate vis.js components directly in your webpack build



You can integrate e.g. the timeline component directly in you webpack build.

Therefor you can e.g. import the component-files from root direcory (starting with "index-").



```js

import { DataSet, Timeline } from 'vis/index-timeline-graph2d';



var container = document.getElementById('visualization');

var data = new DataSet();

var timeline = new Timeline(container, data, {});

```



To get this to work you'll need to add some babel-loader-setting to your webpack-config:



```js

module: {

  module: {

    rules: [{

      test: /node_modules[\\\/]vis[\\\/].*\.js$/,

      loader: 'babel-loader',

      query: {

        cacheDirectory: true,

        presets: [ "babel-preset-es2015" ].map(require.resolve),

        plugins: [

          "transform-es3-property-literals", // #2452

          "transform-es3-member-expression-literals", // #2566

          "transform-runtime" // #2566

        ]

      }

    }]

  }

}

```



There is also an [demo-project](https://github.com/mojoaxel/vis-webpack-demo) showing the integration of vis.js using webpack.



## Test
