My device must be able to show a simple diagram on a screen of an ordinary computer monitor. I've found display drivers which could do the job, but they seem to be much more sophisticated than I would need. There are some drivers from Epson, but they have hardware acceleration, sprites and much more. I only need some circles and lines. My diagram wouldn't even need to be refreshed more than every ten seconds or so.

Is there any simple display drivers?

Apparently, VGA is pretty easy to render with an AVR microcontroller. Some examples:
