Also look at implicitplot  ?implicitplot

Not to mention breaking up the flow of posts many people don't like to see.

@John May  ahhh, yes okay I see now.  Thanks.  and Ironically I was the one who wrote a post on that.

Curious, everyone has come up with some great answers, and much better than the one I came up with, to the background and finally some closure to this question. 

I ask myself this, how come it took so long?  My only answer is perhaps this question just needed a different perspective or approach to the answer?

@John May actually in Maple 12 when combining implicitplot and plot the plot takes on the ragged implicitplot graphing.   I should mention that in the answer.

Glad to see you got it working.  I believe it was Paul Weiss who was the one who wrote the package, it performs a Delauny triangulation in the xy plane and plots the resulting triangles.  Something like this should be included in the main package of Maple since it seems like many people are interested in using data in this manner.

@David 

aa:=convert(a,listlist)

tac := Triangulate(aa, transparency = .5)

display(tac);

use / slashes instead of \ slashes

hmm, it's been a while.  I can't remember how I figured out to get my code working.  I'll see if I can remember and help you out but it will be a while unless someone else can help you in the meantime.

That is exactly what I wanted!

Thanks Robert
