Dear sage-developers, as Markus said, JSXGraph is a viewer for the web browser: it can a) display geometric construction in the GEONExT file format (http:// geonext.de) or the evolving Intergeo file format (http://i2geo.net/), b) display constructions coded directly in JavaScript. This second point b) may be the interesting part of JSXGraph for sage. The URL http://jsxgraph.uni-bayreuth.de/wiki/index.php/Analyze_data_with_the_Statistics_software_R contains an example where on every mouseUp event data is sent from the client to some high-level functions of the statistics package R on server side. Finally, the result of the R computation is sent back to the web browser and the construction is updated accordingly. The client-server connection is easily done with AJAX. Hopefully, this is one step closer to Robs idea of a tool for output and *input*.
