I study cartogram design. Cartograms are thematic maps in which the enumeration units (states, countries) are resized based on a particular attribute (population, carbon emissions). There are dozens of types/designs of cartogram and many methods/algorithms for cartogram production.
These have gotten a lot of attention lately (uses the Gastner-Newman diffusion-based algorithm).
Some cartographers manually [...]
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 [...]
Part 2 of what will now be an ongoing series about my work with the Dorling circular cartogram algorithm; see part 1
Above (top) you see the current results of my reworking of the brilliant circular cartogram algorithm by Dr. Daniel Dorling (image on the bottom is from my Python port of Dr. Dorling’s original algorithm, [...]
