Especially if that data is part of a simulation we are toying with. Therefore, this proposal is for: A gnuplot-, matlab- or plotinum-like plotting API (that uses diagrams as the backend?).

Not to throw cold water on these ideas (which sound fantastic!), but
the scope of this sounds more like a GSoC project than something a
beginner could accomplish in 10-15 hours in the space of a few weeks.
I'm looking not for project ideas but for small, concrete
contributions they could make to existing open source projects.
