I think you shouldn't implement the algorithm directly. Rather look for a 
library that does it for you.

If you are using PIL like in the link you give above consider using the 
draw.arc() function directly:

There is also cairographics where you draw a "path" on a "surface".

Sorry, I can't help with the details.
