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. 160 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

Usage
-----

Include 

* `jsxgraphcore.js` and 
* `jsxgraph.css` and, 
* if required, one or more file readers 

from a CDN or a local version in your HTML file. 

For developing content, it is recommended to include `jsxgraphsrc.js` (`jsxgraphcore.js` is the minified version of `jsxgraphsrc.js`).
For further usage instructions please consult our [wiki](https://jsxgraph.org/wiki/)
especially our [tutorials](https://jsxgraph.org/wiki/index.php/Documentation)
or [the API reference docs](https://jsxgraph.org/docs/).

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

1) Clone this repository or download the zip file.

2) In order to build and develop *JSXGraph* you need [node.js](https://nodejs.org/) 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 `$ make core` which will output an unminified version ```jsxgraphsrc.js```  and the minified version ```jsxgraphcore.js``` in ```distrib```.
