If the export function is implemented in Subsurface, then all this data
should be available and can be included in the produced output. So the plan
is to have this output possibility as part of the result on this GSOC
project. Even better, if the HTML/JS part is almost there.

I am not the one to make any decisions on license issues, but at least
Highcharts is free for non-profit use and allows redistribution and code
modifications for non-profit software. (We just need to mention that
Highcharts is not free for commercial use and provide link to their web
site.)

Looks good. We just need to produce the HTML/JS from Subsurface with easy
to use interface, and no additional packages or installations (like PHP
would be in your current implementation), all self contained in Subsurface
installation package. As Dirk remembers to state, our average user is not
computer specialist :D
