I am trying to gen up support to get jsxgraph included at cdnjs and would appreciate it if all you math types would go to their forum and vote for this:

You can cast three votes for this and given all the whiners that are lurking here we should have 150 votes in no time....
What is this all about? CDN js is a service that allows one to access js libraries via "the cloud", much as MathJax has done via Amazon. In this way one can download and install the libraries for jsxgraph locally, or simply include a reference to them in your SEE configuration (and if you don't know what SEE is you need to look in the docs under Advanced Math Tools - lol.) If we can get these Math libs all in teh cloud, then we can write plugins to look for the libs in /lib and if they are not there to source them automagically from the appropriate online location. This takes us one more step towards transparency and universality
