JSXGraph is a cross-browser library for interactive geometry, function plotting, charting, and data visualization in a web browser.

• Supported file formats: GEONExT, Intergeo

• Tailored "Mathlets" can be created using JavaScript
• JSXGraph runs on practically every web browser starting from IE 6
• JSXGraph runs on all major operating systems including MS Windows, Apple Mac OSX, Linux, iOS, Android.

From a technical point of view, JSXGraph is implemented completely in JavaScript and does not rely on any other library. JSXGraph uses a web browser's SVG, VML, or canvas engine for graphics rendering. At the moment, the size of the library is approximately 83 kByte. Further references: http://jsxgraph.org.
