Integration of Visualizzation Tools for graph

[ZigRazor]

hi @FlyinCow ,
thank you for the question.
Actually there is no mechanism integrated to visualize graph.
In any case is possible to export DOT file to visualize the graph in graphviz.
In the next future we want to introduce support to visualize graph integrated with graphviz.
