Voronoi Territory Map

status="ready" · 12 depots divide a fixed 120 km × 90 km region; every border sits halfway between two of them, so a cell is exactly the ground closest to its depot. Fills only keep neighbours apart — the share is printed. Hover a cell (or Tab in and use the arrow keys) to lift it.

Fills only keep neighbouring territories apart — they encode nothing. Size is the value, and each cell that has room prints its own share.

Every territory in Depot catchment, largest first. Positions are seeds, not the centres of the territories they own.

status="empty" · a valid payload with not one depot in it, told apart from "loading" and "the fetch failed".

Depot catchment

Catchment by straight-line distance

Nothing to divide yet

A tessellation needs at least one depot with a position on both axes.

status="loading" · a mosaic skeleton built by the same tessellator from a hard-coded seed list — nothing random, aria-hidden, no timer.

status="error" · the fetch failed; "Try again" only appears when onRetry is passed, and clicking it switches to ready.

The data source didn't respond.

Degenerate data · one depot: both domains are fitted, so the zero-width span is padded by ±50% before there is a frame to divide, and the single territory claims all of it — 100%, rank 1 of 1, no borders.

Pilot region · one depot, nothing to divide against

Degenerate data · two depots on the same coordinates (only one can own the spot, the other is listed with no territory), one with an unusable position (dropped and counted), one outside the fixed region (it still claims the ground nearest to it, and an arrow on the frame points at it) and one name far too long for its cell (elided to what fits; the full name stays in the tooltip, the readout and the table).

6 depots · largest 22% · smallest 1.7%

Fills only keep neighbouring territories apart — they encode nothing. Size is the value, and each cell that has room prints its own share. 1 depot hold no territory: 1 standing on another seed. 1 depot had no usable position and is not drawn. 1 depot sit outside the plotted range; they still claim what is nearest to them, and an arrow on the frame points their way.

weighting="power" · the same twelve depots, borders weighted by daily capacity: each border leaves the midpoint by (r₁² − r₂²) / 2d, so the busiest depots reach further and the smallest cells shrink to a few percent. Cells stay convex, because power distance still cuts along straight lines. Push weightStrength to its 1.5 ceiling and the smallest depots are swallowed outright — then they are reported as holding no territory rather than vanishing.

Fills only keep neighbouring territories apart — they encode nothing. Size is the value, and each cell that has room prints its own share. Borders are weighted by daily capacity, so they sit off the midpoint between two seeds.

onSelect · pass it and every territory stops being role="img" and becomes a real button. The arrow keys walk the borders rather than a grid: from a focused cell they move to the neighbour that lies most nearly in that direction, and Home / End jump to the largest and smallest territory.
