Hi Tobin, Just a fellow heroku user like you.
GraphViz does such great stuff. The layout is just great. Display is not as nice as something like OmniGraffle, but the layout is superior. (I think OmniGraffle hired the guy from AT&T, and is doing great stuff merging the concepts between the two products. But it still has a little way to go. e.g.: it doesn't support different layouts for different subgraphs which is something that GraphViz does wonderfully) But I do wonder what it would be like to separate the layout from the generation. Of course if that layout would be best done in ruby. :) Looking at the dependencies, wonder if they use TCL to do that work. --Keenan On Apr 17, 2009, at 6:31 PM, Tobes wrote: > > Again, thanks for considering all this. > > Keenan, I'll keep searching, and if I can delegate #2 (create > graphics) to something like imagemagic then that would be awesome.
