This output is a good start and should work fine as a first template that
can be used when implementing HTML output in all other modules.
Once this is done we can work on adding some interactivity. However; it
might be a good idea to just release a version with some simple HTML
output before adding more complex stuff.
Flot is a javascript plotting library for charts. It uses JQuery, is very
common and has a good compatibility between different browsers.
We will use this library for data representation in the HTML output mode.
