Just knocked a quick script up to read in an excellon drill file and display it using pygoocanvas:
The lines show the path in the file. Tool changes aren’t yet shown.
Source coming later. After sleep.

Good work! What’s going on with the line of small holes near the top left? No connecting paths.
That looks pretty well optimised.
