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 in your HTML

file. 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 of ```jsxgraphcore.js``` in ```build/bin```. To build a minified version run `$ make core-min`. This will produce the files `jsxgraphsrc.js` (not minified) and `jsxgraphcore.js` (minified) in directory `distrib`.
