If you mean 100 graphs per second, I don't think commodity PC hardware
will do it.

Displaying 1 graphs/second, might be more reasonable, depending on the
quality of graph you want.  Gnuplot is the canonical answer.  But, if
you want fast character plot on your terminal (just for visual check),
then you could probably display more than 1 graphs/second.
