In the past we have used the Visio API to export Understand’s graphs to Microsoft Visio. Understand would attempt to launch Visio and use the API to interactively draw the graph in Visio. There were several problems with this approach, the nodes and arrows of the graphs were not adequately connected, and in some cases the API would refuse to launch Visio. Of course this approach also required that Visio itself be installed on the same system as Understand.
Some graphs also have an option to export to the graphviz .dot format. This option is only available to newer graphs that are generated using the graphviz engine in Understand. Some older graphs use a different layout engine so that option is not available for them.
