The Data City

Everything on the shelves, in 3D.

Why
Two sunset harvests (2026-08-04 + 08-15) froze the whole survivorship-free record — including the ~12.5k companies that died, the ones a normal data feed quietly forgets. The frozen quarters are the bedrock, the proof the record can never lose — and the city keeps building past them. This is a picture of all of it.
Live
The city is alive: the Sharadar Core US Equities bundle (Nasdaq Data Link) still feeds the shelves — daily prices (stocks + funds, dead ones included), point-in-time valuations, and fundamentals land as new quarterly chunks; 13F institutional holdings arrive ~46 days after each quarter ends (the filing embargo). Every new chunk is a new building on its street, walked in by the next census.
How
Every building is one file on disk. Avenue = table family · street = time, 1998 → 2026 · height = rows (log scale). Nothing is sampled: the census walked all files once and measured them.
Read
gold = the terminal _final_ snapshots taken on harvest day · faint outlines = pre-harvest stale partials, kept as ghosts · the tall dense blocks are daily prices, the sparse ones are fundamentals.
Drive
Drag to orbit · pinch / wheel to zoom · two-finger drag or shift-drag to pan · tap a building for its census card. It idles into a slow orbit when you let go.
