Here is the world famous scatter plot offered to demonstrate 
the "plotting" ease that GW-BASIC offers.  This is a real 
life set of data for the California Department of Fish & 
Game.  Scatter plots are very heuristic.  Don't try this 
with Excel, Lotus, Quattro or most if not all big buck 
spreadsheets.  Mathematica might be a good candidate if you 
have money falling out of your pockets as an undergrad.  
GW-BASIC is 80k and substantially free nowadays.

This eleven liner took about an hour or so to program.

Entering the damn data and making sure that it was right 
took more time than writing the program.

so here it is:
