Supply chain and logistics
Where it is, where it was going.
This is the one discipline of the five that starts on the map rather than the graph. The network still matters — it is where the single points of failure are — but the question usually begins as a geography.
A geography, and the network under it.
Map-first
Weighted flows between places, width by volume, with edge bundling that groups parallel routes into visible corridors. Bundling runs in projected world space, so it stays correct at every zoom instead of re-bundling on each pan.
Tracked movement
Entities with interpolated positions between samples, and trails behind them. Interpolation is strictly between known samples — we do not invent a position beyond your data, because on a map an extrapolated position is a false claim about where something was.
Clustering by zoom
A dense port is one marker labelled with a count rather than four thousand overlapping markers.
Schedule against actual
Both on one timeline. Brush a window and the map shows only what moved in it.
Single points of failure
The dependency graph, with betweenness over it. The supplier everything routes through is the one the algorithm finds, not the one someone remembered.
Unplaced data
Entities with no coordinates go into a side panel rather than at zero-zero in the Atlantic. A missing location is a fact about the data, and it should look like one.
