Graph representation of configs in ve_run.toml

Is your feature request related to a problem? Please describe.
When we add python functions to visualise to tidy outputs, it'd be great to also include a simply function to draw the dependencies or flow between modules as configured in ve_run.toml. I think some users will use it to visually check that they have configured the dependencies correctly, before running the simulation.

The documentation of config/ve_run.toml was simple, but the example tutorial reveals init = and update = . We should explain this in the tutorial page, and a graph would be helpful for the explanation.

Describe the solution you'd like
A simply python function to read ve_run.toml and generate a dependency flow chart.
