1. Flot

Flot is a pure Javascript plotting library for jQuery. It produces graphical plots of arbitrary datasets on-the-fly client-side.

The focus is on simple usage (all settings are optional), attractive looks and interactive features like zooming and mouse tracking.

The plugin works with Internet Explorer 6/7/8, Firefox 2.x+, Safari 3.0+, Opera 9.5+ and Konqueror 4.x+ with the HTML canvas tag (the excanvas Javascript emulation helper is used for IE).

4.dwpe

dwpe chart is accessible charts and graphs that uses JavaScript to scrape data from an HTML table and generate bar, line, area, and pie chart visualizations using the HTML5 canvas element. This technique provides a simple way to generate charts, but more importantly, because it bases the chart on data already in the page in an HTML table element, it is accessible to people who browse the web with a screen reader or other assistive technology, or with browsers that don’t fully support JavaScript or HTML5 Canvas.
