The vis npm package is a dynamic, browser-based visualization library. It is designed to handle large amounts of dynamic data and enables the creation of interactive timelines, 2D/3D graphs, and network visualizations.
Timeline
The Timeline feature allows you to create interactive timelines with items that can have start and end dates. This is useful for visualizing events over time.
const vis = require('vis');
// Create a DataSet (allows two way data-binding)
var items = new vis.DataSet([
{id: 1, content: 'item 1', start: '2023-04-20'},
{id: 2, content: 'item 2', start: '2023-04-14'},
{id: 3, content: 'item 3', start: '2023-04-18'},
{id: 4, content: 'item 4', start: '2023-04-16', end: '2023-04-19'},
{id: 5, content: 'item 5', start: '2023-04-25'},
{id: 6, content: 'item 6', start: '2023-04-27', type: 'point'}
]);
// Configuration for the Timeline
var options = {};
// Create a Timeline
var timeline = new vis.Timeline(container, items, options);Network
The Network feature allows you to create interactive network graphs with nodes and edges. This is useful for visualizing relationships and connections between entities.
const vis = require('vis');
// 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},
{from: 1, to: 2},
{from: 2, to: 4},
{from: 2, to: 5}
]);
// create a network
var container = document.getElementById('mynetwork');
var data = {
nodes: nodes,
edges: edges
};
var options = {};
var network = new vis.Network(container, data, options);Graph2D
The Graph2D feature allows you to create interactive 2D graphs. This is useful for visualizing data points over a two-dimensional space.
const vis = require('vis');
// Create a DataSet (allows two way data-binding)
var data = new vis.DataSet();
// Add data
for (var i = 0; i < 100; i++) {
data.add({x: i, y: Math.sin(i / 5)});
}
// Configuration for the Graph2d
var options = {
start: '2023-04-10',
end: '2023-04-30'
};
// Create a Graph2d
var container = document.getElementById('mygraph');
var graph2d = new vis.Graph2d(container, data, options);D3.js is a JavaScript library for producing dynamic, interactive data visualizations in web browsers. It uses HTML, SVG, and CSS. Compared to vis, D3.js offers more flexibility and control over the visualizations but requires more effort to set up and use.
Chart.js is a simple yet flexible JavaScript charting library for designers & developers. It offers a variety of chart types and is easy to use. Compared to vis, Chart.js is more focused on traditional chart types like bar, line, and pie charts, and is less suited for complex network or timeline visualizations.
Cytoscape.js is a graph theory library for visualizing and analyzing networks. It is highly customizable and supports a wide range of graph layouts. Compared to vis, Cytoscape.js is more specialized for network visualizations and offers more advanced features for graph analysis.
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:
The vis.js library is developed by Almende B.V.
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.
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.
require.config({
paths: {
vis: 'path/to/vis',
}
});
require(['vis'], function (math) {
// ... load a visualization
});
A timeline can be instantiated as:
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 of the project.
<!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>
To build the library from source, clone the project from github
git clone git://github.com/almende/vis.git
The project uses jake as build tool. The build script uses Browserify to bundle the source code into a library, and uses 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:
npm run build
To test teh library, install the project dependencies once:
npm install
Then run the tests:
npm test
