Vis.js is a dynamic, browser based visualization library.The library is designed to be easy to use, handle large amountsof 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:
    $ npm install vis
Install via bower:
    $ bower install vis
Link via cdnjs: http://cdnjs.com
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<!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.
```jsrequire.config({  paths: {    vis: 'path/to/vis/dist',  }});require(['vis'], function (math) {  // ... load a visualization});```

A timeline can be instantiated as:
```jsvar 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 thecomponent.

## Example

A basic example on loading a Timeline is shown below. More examples can befound in the [examples directory](https://github.com/almende/vis/tree/master/examples)of the project.
```html<!DOCTYPE HTML><html><head>  <title>Timeline basic demo</title>  <script src="vis/dist/vis.js"></script>  <link href="vis/dist/vis.css" rel="stylesheet" type="text/css" />
  <style type="text/css">    body, html {      font-family: sans-serif;    }  </style></head><body><div id="visualization"></div>
<script type="text/javascript">  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);</script></body></html>```
## Build

To build the library from source, clone the project from github
    $ git clone git://github.com/almende/vis.git
The source code uses the module style of node (require and module.exports) toorganize dependencies. To install all dependencies and build the library,run `npm install` in the root of the project.
    $ cd vis    $ npm install
Then, the project can be build running:
    $ npm run build
To automatically rebuild on changes in the source files, once can use
    $ npm run watch
This will both build and minify the library on changes. Minifying is relativelyslow, so when only the non-minified library is needed, one can use the`watch-dev` script instead:
    $ 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`:
  ```  $ [sudo] npm install -g browserify babelify uglify-js  ```
- Download or clone the vis.js project:
  ```  $ git clone https://github.com/almende/vis.git  ```
- Install the dependencies of vis.js by running `npm install` in the root of the project:
  ```  $ 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:
```jsexports.DataSet = require('./lib/DataSet');exports.Timeline = require('./lib/timeline/Timeline');```
Then create a custom bundle using browserify, like:
    $ browserify custom.js -t babelify -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:
    $ uglifyjs dist/vis-custom.js -o dist/vis-custom.min.js
The custom bundle can now be loaded like:
```html<!DOCTYPE HTML><html><head>  <script src="dist/vis-custom.min.js"></script>  <link href="dist/vis.min.css" rel="stylesheet" type="text/css" /></head><body>  ...</body></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:
    $ browserify index.js -t babelify -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:
```html<!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>```
#### 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:
```jsvar 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:
    $ 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<!DOCTYPE HTML><html><head>  <link href="node_modules/vis/dist/vis.min.css" rel="stylesheet" type="text/css" /></head><body>  <div id="visualization"></div>  <script src="dist/app-bundle.min.js"></script></body></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 just import the component-files from root direcory (starting with "index-").
```jsvar visTimeline = require('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 the some babel-loader-setting:
```jsmodule: {	loaders: [{		test: /node_modules[\\\/]vis[\\\/].*\.js$/,		loader: 'babel',		query: {			cacheDirectory: true,			presets: ["es2015"],			plugins: [				"transform-es3-property-literals",				"transform-es3-member-expression-literals",				"transform-runtime"			]		}	}]}```
## Test

To test the library, install the project dependencies once:
    $ npm install
Then run the tests:
    $ npm run test
