Sorry, I've been rather lax on this :( I got dragged onto other stuff,
went on training courses, and all sorts of other things.

That's all very easy for you to say :))

Well, wikipedia suggests the following[1] (and goes into further detail
as well[2])
| Current State -> | State | State | State |
| Input v | A | B | C |
|------------------+-------+-------+-------|
| x | B | ... | ... |
| y | ... | C | ... |
which basically says that when the machine is in State A and receives
'x' then it transitions to State B, and when it receives a 'y' in State
B it transitions to State C.

Okay. What should this python code here do? :) I know, it converts a
table to dot-script, but are there any examples I could look at which
take a table as input and output something (anything), just so I can see
how the python code should expect its input?

Sure :)
