You still haven't really given any information about your goals.  Is
this program just for visualization of static data?  Anything dynamic?
Who's the audience?  Do you need to do printing of the same output?
How precisely does the printed version need to match the screen?
Is this part of a program that you will be giving to others, or
is it just for personal use?  Do you have any limitations with respect
to the platform used?  Linux only?  Windows only?  Both?  Neither?

And you can probably add another dozen questions to the mix.

Yes, I understand that you hope someone can say something like 
"Use X or Y, but skip Z because it sucks", but you really can't
expect to get a to-the-point answer if nobody knows what you want
this for.
