[gradsusr] Shapefile

[Jennifer Adams]

Have a look at ftp://iges.org/grads/scripts/shp_demo1.gs

What you need to do is use the 'q dbf' output to loop over each shape  
in your file, decide on the fill color to use based on the data base  
value for that shape, then draw it individually. It's a little slow,  
but effective.
