Many drawing tools support SVG as a file export format. Exporting or
converting the map to SVG format allows the map attributes (link
As an example, the following SC15 weathermap was created by converting
a PDF diagram of the network into an SVG file:
The code is on GitHub and it wouldn't be hard to re-purpose:
The ESnet weathermap is very cool and they have open sourced the code:
