We’ve got a pretty complex graph in an Access DB stored as nodes (node1, node2, etc.) and edges between the nodes (n1->n2 etc.).
We’d like to visualize this in an MS Access application. What “graphics packages” would you suggest? How can these be integrated into Access? We’re currently using Access 2002.
NOTE: A tree control is not sufficient as we have a more general graph (if you displayed our graph as a tree one node would occur multiple times).
It depends what you want your Graph visualisation to do, if it is just a picture then you could try using a command line based package like GraphViz. You’d just need to write a macro to invoke GraphViz, output your Graph in the DOT syntax to the GraphViz command line and then display the generated image in Access using a Form.
If you want an interactive visualisation of your Graph I’ve never used any such package myself so can’t recommend one but I’m sure there are some out there.
