I'm starting to make heavy use of WBS diagrams. Thanks. Marvellously simple syntax.
1) Obviously the main label is the top box, but it'd be handy to put a "graphviz style" label somewhere on the diagram (e.g. for version and date information).
2) I make use of colour (via <style>) to, for example, indicate priority activities in the work breakdown, but I'd like to make a small key using coloured boxes at the bottom left or right ... below the main diagram ... it'd be nice to have a syntax for boxes which would appear all in a horizontal row, unconnected, but justified (left/right/centre) with respect to the main diagram.
Best wishes, Bryan
