Building topology in Flash

For a while now, I’ve wanted to build geographic topology in Flash. Topology, as described in an ESRI white paper, is
a set of rules and behaviors that model how points, lines, and polygons share geometry. For example, adjacent features, such as two counties, will share a common edge.
For the applications I’ve had [...]

i got better

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 [...]

mine is more like poorling

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, [...]
