Graphviz rendering from within the logic program

[sahil1105]

Develop convention similar to %schema and %temporal to be able to quickly detect graph like problems and hence make graph visualizations easy. eg. maybe have a %node, %edge, conventions for what to color and how, etc.

[sahil1105]

Ideas: %graphviz graph rankdir=LR ..... %graphviz node relname(_,_,N,\) ord=1 label=$3 color=red shape=box style="rounded,filled" .... %graphviz edge relname(\,E) directed ord=3 color=$1 ......

N --> this attribute defines the node name $ --> means defined variable ord --> style preference (higher ord --> more preference)
