JavaScript Charts Roundup

Flot

Flot is a jQuery-based JavaScript plotting library, which focuses on simple usage. The results are fairly attractive, and has some interactive features, such as zooming. It works with all modern browsers (including IE6+, where Google’s ExCanvas is used). If you’re into Prototype, check out Flotr, a Prototype port.

jqPlot

This is another jQuery plugin, and produces results not dissimilar to Flot. It provides quite a wide range of graphing options.

dojo Charts

Dojo Charting, part of the Dojo Toolkit, provides many common chart types including line, bar, area and pie charts.

Bluff

Bluff is a James Coglan’s JavaScript port of Ruby’s Gruff graphing library. It depends on James’ JS.Class (and ExCanvas to support IE).

PlotKit

PlotKit is based on MochiKit, but unfortunately only supports IE6+ via Adobe’s discontinued SVG viewer.

Protochart

Inspired by Flot and PlotKit, Protochart build upon Prototype and ExCanvas, providing a good range of charting options.

Google Visualisations

Google Visualizations provide a variety of ways to represent your data, including charts from the Google Chart API as well as pure client-side visualizations (some of which require Flash).

Yahoo UI Charts

YUI charts let you visualize tabular data on a web page in a variety of different ways, but unfortunately the chart control depends on Flash 9.

Processing

This is not just restricted to charts, and it doesn’t support IE (yet), but I wanted it to include it anyway as, like Raphaël, Processing is such a powerful tool.
