How the cartogram is built
How the pipeline works, in the order it runs. Every figure is generated from the
build artefacts by R/40_doc_figures.R and R/41_method_figures.R, so the
documentation cannot drift from the code: if the pipeline changes, re-running
them changes the pictures.
| Placement | Sizing each state to its seat count, fitting it to the hand-drawn layout, and pushing the country apart until nothing overlaps. Also available as an interactive walkthrough. |
| Carving cells | Subdividing each state into equal-area cells, one per seat: sample, cluster, power diagram, clip. |
| Matching | Pairing each real district with one cell, so the morph between them reads. |
The stages either side of these are thin enough to live in the README: getting and projecting the boundaries at the front, and writing the JSON at the back.
census boundaries -> project + simplify -> scale to seats -> place in slots
-> push apart -> carve into cells -> match cells to districts -> JSON
