In my experience  I always just use an external program to generate the graph  mathematica  gnuplot  matlab  etc   and export the graph as a pdf or eps file   Then I include it into the document with includegraphics

Aside from the  excellent  suggestion to use TikZ  you could use gastex  I used this before TikZ was available and it did its job too

I have used graphviz   https   www graphviz org gallery   together with LaTeX using dot command to generate graphs in PDF and includegraphics to include those    If graphviz produces what you are aiming at  this might be the best way to integrate  dot2tex  https   ctan org pkg dot2tex lang en
