A four-state badminton flight-signature chart in hand-rolled SVG — the full 13.40 m court seen from the side with a to-scale net at centre, each stroke type aggregated into a median parabolic arc with a p25–p75 band, dash patterns as second identity, landing marks on the floor and physics guards that lift impossible arcs over the cord.

The court from the BWF book, seen from the side: 13.4 m end to end with the net at the centre, drawn 1.55 m tall — its height at the posts; the cord sags to 1.52 m at the centre strap, which one elevation cannot show. The floor is ticked every metre, with the opponent's short service line at 1.98 m and the doubles long service line at 5.94 m past the net. Each stroke's arc is the parabola through its median contact, apex and landing; the wash spans the arcs built from the quartile apex and landing, and every flight leaves its landing mark on the floor. An arc whose numbers imply a flight through the net is lifted just enough to skim the cord — the shuttle landed beyond it, so it crossed. Point at an arc — or press Tab and walk the strokes with the arrow keys — to read one signature.
1 row dropped: a landing at or behind the net — the shuttle never crossed, so there is no flight to draw. 1 apex arrived below its own contact height and was raised to it.
Shuttle trajectory: D. Wardani, Women's singles · semi-final. The full 13.4 m court seen from the side — the hitter's half on the left, the net at the centre drawn 1.55 m tall (its height at the posts; the cord sags to 1.52 m at the centre). 25 flights across 5 stroke types, each aggregated into a median arc with a band between its quartile arcs; landing marks sit on the floor at every flight's depth. Clear: 7 — apex 6.3 m, landing 6.2 m past the net. Drop: 6 — apex 3.2 m, landing 1.6 m past the net. Smash: 6 — apex 2.9 m, landing 4.5 m past the net. Drive: 5 — apex 1.9 m, landing 5.1 m past the net. Net shot: 1 — apex 1.9 m, landing 0.8 m past the net. Exact figures follow in the data table.
Every stroke type in its fixed order, with how many flights it aggregates, the median contact point, the median apex as drawn and the median landing depth past the net.
