Reducing SVG file size in JSXGraph
By Murray Bourne
Following on from the Point animations efficiency page, I believe the board construction and point movement for those examples would be faster if the resulting file sizes (and number of empty elements) were reduced.
This page illustrates the original output, then a stripped down version keeping all the empty DIVs, and then finally the slimmest version with a suggestion for points using classes.
Consult the page source to see the differences.

I've removed all invisible elements, like point labels.
Also in this case, I've reduced the (unnecessary) number of decimal characters (15 places) for the <path> element, from (.e.g.)
d="M 0 0 L 302 0 M 0 11.615384615384613 L 302 11.615384615384613 M 0 23.23076923076924 L 302 23.23076923076924 M 0 34.846153846153854...
... to 2 decimal places ...
d="M0 0L302 0M0 11.62L302 11.62M0 23.23L302 23.23M0 34.85...
