Equation Tree javascript libraries

Equation trees are described in the following link, the idea is depreciated in my opinion based on Volkers semantic tree implementation at the bottom of the email not being as good as I'd hoped which is an implementation of the idea.

The following links could help implement equation trees.

Hi Denis,

While this might not be directly related to your proposal, you might find the following formula tree visualisation interesting: 
The displayed trees correspond to the semantically richer structure that my speech rule engine uses internally and that we use in MathJax to voice formulas.


Also, you might consider the \texttip and \mathtip macros in "action" extension for TeX input (if you are using TeX):

or the <maction actiontype="tooltip"> element if you are using MathML input.  These will display a tooltip when you hover over an element, so that might be what you need to expand variable names into longer descriptions.
