Cytoscape.js is a library for data analysis and visualization, compatible with Node, jQuery and vanilla JS.

Cytoscape.js allows users to interact with the graphs so it’s inherently useful for visual data analysis.

It supports desktop and mobile browsers alike, making it an ideal candidate for web applications.

The library is meticulously documented, and pretty complex as well.

Plot.ly is a web app for analyzing and sharing data.

Plot.ly allows creating data graphs ready for publishing (it has been featured in The Washington Post and other journals).

Basically, Plot.ly is a dedicated app for creating graphs that can serve you better than many desktop alternatives.

Chartkick is a Ruby gem (also available as a jQuery plugin) for creating charts easily.

Chartkick allows making the most common types of charts in seconds, thus allowing you to focus on getting the data, not writing the code.

It works on most browsers, including IE6, which is quite a feat for any modern library.

Chart.js is a library for creating object-oriented client side graphs.

Chart.js has six chart types that can be used with a simple and flexible library. Chart.js weighs only 4.5kb when minified and offers numerous customization options.

What’s most impressive about this HTML5 based library is that it supports a great number of animations — always useful for making your charts all the more attractive.

Flot is a chart plotting library made with jQuery.

Flot supports different types of input data. It can print lines, points, filled areas, bars and any combinations of these.

Not only that, but Flot supports real-time updates as well, and altogether looks like a rather comprehensive toolset for plotting charts.

Multigraph is a JS library for creating advanced pannable graphs.

Data is passed to Multigraph as XML; there aren’t a lot of options but the functionality so far is impressive — for example, Multigraph offers two ways for the user to pan the data to make more sense of it.

While it’s easier to create graphs with HTML, the library also offers using JavaScript for graph creation.
