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.
Filter and order items and convert fields of items.
- Timeline. Display different types of data on a timeline.
The timeline and the items on the timeline can be interactively moved,
zoomed, and manipulated.
- Graph. Display an interactive graph or network with nodes and edges.
The vis.js library is developed by [Almende B.V](http://almende.com).

Install via npm:
npm install vis
Install via bower:
bower install vis
Or download the library from the github project:
[https://github.com/almende/vis.git](https://github.com/almende/vis.git).
To use a component, include the javascript and css files of vis in your web page:
<!DOCTYPE HTML>
<html>
<head>
<script src="components/vis/dist/vis.js"></script>
<link href="components/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.
```js
require.config({
});
require(['vis'], function (math) {
});
```
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.
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
<!DOCTYPE HTML>
<html>
<head>
<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>
```
To build the library from source, clone the project from github
git clone git://github.com/almende/vis.git
The project uses [jake](https://github.com/mde/jake) as build tool.

The build script uses [Browserify](http://browserify.org/) to
bundle the source code into a library,
and uses [UglifyJS](http://lisperator.net/uglifyjs/) to minify the code.
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.
cd vis
npm install
Then, the project can be build running:
## Test
To test teh library, install the project dependencies once:
npm install
Then run the tests:
npm test
