Although the iMindMap documentations does not seem to mention this, it is quite simple to develop stand alone flow charts that are easily formatted in iMindMap.

And,  if you want a 3D diagram just click the button.

Making concept maps, scientific path diagrams, flow charts, and other kinds of general diagrams is VERY easy and fast.  [Note: You can combine mind maps and other types of diagrams together. Or you can do a diagram without a mind map. And very rapidly with great control over format. And 3D.]

No April Fool here.
