How to visualize causal relationships?

Question

Design

Hey!
I am looking for a program, service, solution for visualizing cause-and-effect relationships for building flowcharts of large algorithms. Preferably 3D or 2D with good dependency display functionality.
How I see it:
Task - several solution paths - paths are divided into steps - steps can go from one solution path to another at any place. Those. step #3 of path #1 goes to step #4 of path 1 and step #7 of path 3 and vice versa.
Visualization: a three-dimensional flowchart that displays many options for dependencies with arrows, etc., which can be rotated, viewed without losing the overall picture, move steps to different zones, stages, add different levels of connections. A tag cloud for example comes to mind. Or a card with photos and threads like in detective stories.
Thank you for your attention.

Answer 2

What you need is called a dependency digraph. It can be visualized using any graph visualization tool. But you will be forced to compose these dependencies somehow.

Answer 3

There is a book, electronic and paper, I bought both of them, by Vladimir Parajanov.
" Learn to Write, Read and Understand Algorithms" , subtitled "Algorithms for Correct Thinking".
Very good "puts his head in place" in this matter.
It is about the correct and convenient, easy-to-read graphic representation of algorithms.
And about the DRAKON language (software was written on it, in graphical form, for our reusable ship "Buran")
There is software for visualization under Windows (in other words, I use it on a Mac).
The authors sell it inexpensively (I don’t remember how much it cost, but somehow it was unprincipled for me, even though I paid out of my own pocket)
I highly recommend it.
I also recommend just mind maps ( MindMap ), there is an excellent Free solution for popular platforms, this is XMind . It is better than many paid solutions. Although there is a paid version for XMind too.
