- Worth noticing
- The random-map sampler requires connected ridings and limits each riding to within 25% of average population.
Field notes
Each voter dot represents about 100 people who voted in 2023, placed in their neighbourhood; orange and blue distinguish NDP and UCP votes. The page describes a recombination sampler that merges neighbouring ridings before randomly splitting them, and compares runs that may cut Lethbridge with runs that try to keep the city intact. It links to rebuilt riding boundaries in GeoJSON, riding results in CSV, and method notes.
