Highcharts is a charting library written in pure JavaScript, offering an easy way of adding interactive charts to your web site or web application. Highcharts currently supports line, spline, area, areaspline, column, bar, pie and scatter chart types.
It works in all modern browsers including the iPhone and Internet Explorer from version 6. Standard browsers use the Canvas element and in some cases SVG for the graphics rendering. In Internet Explorer graphics are drawn using VML.
Highcharts is solely based on native browser technologies and doesn’t require client side plugins like Flash or Java. Furthermore you don’t need to install anything on your server. No PHP or ASP.NET. Highcharts needs three JS files to run: The highcharts.js core, a canvas emulator for IE, and either the jQuery or the MooTools framework. One of these is most likely already in use in your web page.
