JSXGraph
========

JavaScript library for interactive math visualizations in the web browser.

About
-----

JSXGraph is a cross-browser library for interactive geometry, function plotting,
charting, and data visualization in a web browser. It is implemented completely
in JavaScript, does not rely on any other library, and uses SVG, canvas, or even the venerable VML.
JSXGraph is easy to embed and has a small footprint: approx. 200 KByte if
embedded in a web page. No plug-ins are required! Special care has been taken
to optimize the performance.

JSXGraph supports multi-touch events and runs on all major browsers, even on very old IEs.

JSXGraph is developed at the
Lehrstuhl für Mathematik und ihre Didaktik
University of Bayreuth, Germany

Build and develop JSXGraph
--------------

1) Clone this repository or download the zip file.
2) To build and develop JSXGraph you need node.js v0.6+. First, install all
dependencies required to build JSXGraph using npm in the JSXGraph root directory: $ npm install.
This will create a new subdirectory `node_modules` in the JSXGraph root directory which holds
all tools and libraries required to build `jsxgraphcore.js`.
3) To build JSXGraph run $ npm run buildCore. This will output an non-minified version jsxgraphsrc.js
and the minified version jsxgraphcore.js into the folder distrib.
4) Develop JSXGraph:
- Edit the source files in the folder src
- Write unit tests in folder test
- Run $ npm run eslint and $ npm run test to check for errors
- Run $ npm run check-format to check the formatting of the source code
- Submit a pull request

Plug-ins
