This plugin for the HexRays decompiler creates a graph of a decompiled function using IDA's internal graph viewer. It zooms in on the graph view to 100%, attaches it to the currently active decompiler window and sets the focus on the item that the decompiler view's cursor points to.
May be helpful for learning about the different c-tree items of a decompiled function which can be used when developing and debugging scripts and plugins for the HexRays decompiler.
The plugin can be run with a decompiler window focused, by pressing the "Ctrl-Shift-." hotkey.
