5000 seems like a lot of lines for one graph, but you could write:

forvalues i = 1/5000 {
	local graphs `graphs' (line yvar xvar if group == `i')
	}
graph twoway `graphs'

A nice introduction to foreach and forvalues loops is Kit Baum's "A little bit of Stata programming goes a long way..." at http://fmwww.bc.edu/ec-p/wp612.pdf . His introductory Stata programming book is also an excellent way to learn such things.
