Cheers, folks. So, just 1.5 months ago I posted my own Python script to load shapefile data. Well, recently — while doing some pretty hardcore shapefile loading + cartogram generation — I realized I had a pretty significant error in my shapefile loading module.
This link (to my corrected shpUtils.py), corrects the mistake. [...]
I’ve talked about this before: Parts I & II.
The above shows the latest results of my circular cartogram algorithm. It’s just a few steps away from being complete, at which point I’ll post the Python code here. Here’s what I’ve done between the First and Latest attempts.
Better definition of “neighbors”.
I now loop through [...]
update: Here’s the dorling.py code, which is just a port of Danny Dorling’s C to Python. Remember, this only works with a particular topological input format (see county.in). I’ve done some more experiments with the circular cartogram algorithm: here, here, and most recently here.
Dr. Daniel Dorling was recently nice enough to provide me [...]
