See the board

This is the instrument.

Below is the DwellDelta control panel, captured from release v0.9.66. Not a mockup, not a redraw — the board as it renders, screenshotted and placed here unedited.

Captures, not a live demo Nothing on this page is interactive and no board code runs here. Every value visible in these images is synthetic — the board says so in its own banner, in every one of them.

As it opens

Australia and New Zealand, one board

Thirty-two subjects across both countries. The measure is chosen one at a time on the left; context layers stack underneath it. Every layer carries its own provenance tag — synthetic, geography, or no source — on the layer itself, so a reader never has to guess which is which.

The DwellDelta control panel. A dark map of Australia and New Zealand with thirty-two labelled city markers, a layer list on the right of the map showing ten measures — nine tagged synthetic and one, building sales history, tagged no source — and a rail of panels beside it showing coverage, provenance, subjects by change, history and regions. A banner across the top reads: SYNTHETIC — no real observation is shown. — The banner is not an afterthought. It is the first line of the board and it names exactly what is invented and what is measured.

The delta

Change is a layer, not a footnote

Switch the measure to change and the markers recolour by direction of movement over the delta window — 1, 3, 6, 12, 18 months or the full series. The name of the product is the thing it puts on the map.

The same board with the change measure selected. City markers are now diamonds coloured by direction — blue for rises, red for falls — and the subjects-by-change panel lists Newcastle at plus 34.6 per cent down to Launceston at minus 24.7 per cent. — Rises and falls are separated by colour and by shape, not by colour alone.

The rail

Panels that say what they do not know

Coverage counts the layers that are measured against the ones that are invented and the ones with no source at all. Provenance breaks the same total down again. Neither is a badge — they are counts, and they move when the data does.

The panel rail. Coverage reads thirty-two subjects, two measured layers, nine synthetic layers, five unavailable. Provenance reads two measured geographies, nine synthetic values, five with no source. Below them, subjects by change, a history sparkline for Sydney, and a regions table for Australian and New Zealand regions. — Nine synthetic, two measured, five with no source — stated as a count on the board, not implied by what is missing.

Provenance of these images

Where these came from

Captured from dwelldelta-app v0.9.66, commit bf227de6308b16f48e59b12810217ae0496be33e.
Served locally from the tagged tree and screenshotted at 1500×950. No editing, no compositing, no retouching.
Recorded in board/PROVENANCE.json, which this site's tests check against this page — if one names a different release from the other, the tests fail.

A live embed would mean vendoring the board's source, which is AGPL-3.0-only and contains code derived from World Monitor, © 2024–2026 Elie Habib. That is a licensing decision, and it has not been taken.
