Key Graph# Features:

• A robust and minimalistic general graphing and CASE tool
• Draws UML 2.0 shapes, connections, &c without forcing UML 2.0 compliance.
• Draws generic mathematical graphs.
• Stores the resulting graph using the GraphML format
• Optionally stores the resulting graph in Microsoft Visio .vsd format.
• 3-D graphs
• Simple, easy-to-use UI.
• Graphing Function Analysis Tools (GFAT):
• Can apply analytical functions to a graph to provide additional information on a graph, such as the source/sink vertex, graph size, graph weight, &c.
• Can apply transformational functions such shortest path and spanning tree algorithms to a graph to produce an entirely new graph.
• Can apply functions that alter the layout of a graph.
• Can apply user-defined functions (via functors) to a graph to do, well, whatever the user wants them to!
