Right, that's a big problem. For my decompilers I wrote a flexible tree
representation of the parse tree with online navigation through the
tree. Source code for Atari ST in GfA Basic has gone long ago :-(

That's not really different. A parse tree only includes more information
(nodes) than the original flow chart of the code.

Another solution may be a structure like used with source code. Blocks
or functions are not arranged LTR but top down. Subtrees are indented
and broken into multiple lines instead of nodes appended LTR.
