The Board, v2: nationwide county map with lenses

Browse Source

The map grew with the data. The old Board showed coverage at the state
level with a Florida drill-down; now that every US county is a demographic
node, the Board renders all 3,109 contiguous counties directly, with
switchable lenses:

  Coverage       — the true fog of war: 67 FL counties lit (officeholders
                   mirrored), the other 3,000+ dark on the frontier.
  Population     — ACS 2023 choropleth, 33 to 9.8M.
  Median income  — k to k.
  Poverty rate   — 1.4% to 48%.

Hover any county for its full readout (demographics + officeholder count).
Self-contained: inlined county geometry (duplicate-point-collapsed),
state-border overlay, hand-rolled projection, event-delegated hover for
3,109 paths, vanilla JS — no external requests. Verified: projection
places counties correctly, 3,099/3,109 join to ACS data.
