> Is this front end code available in a public repository?

Not yet, but you can see the HTML/CSS/JavaScript code from

http://www.tlhiv.org/mpgraph/mpgraph.html

http://www.tlhiv.org/mpgraph/mpgraph.css

http://www.tlhiv.org/mpgraph/mpgraph.js

respectively.  Since I have not cleaned up my code yet, I'm almost
ashamed to put it in a repository.  Perhaps that will come in the near
future.
