IDA Pro already has a function call graph facility, nonetheless it employs WinGraph32.
Although it is helpful, it is not very useful just because it lacks interactivity.
For demonstration purposes, we created a sample plugin that uses the graph functions from the SDK to achieve the same thing but with a bit more of interactivity: double-click to jump to a node, search node by name (also search next), etc…
One can easily modify the plugin to also add a navigation stack or perhaps more filters.
After the plugin is installed it will create a new menu item in Views / Subviews / Function call graph, also make sure you right-click in the graph to see the options and hotkeys.
To recompile the plugin you need IDA Pro SDK version 5.5
Hope you find it useful!
