A four-state tennis groundstroke landing map in hand-rolled SVG — the opponent's half drawn in ITF metres and cut into short / mid-court / deep bands across the left, middle and right thirds, every zone shaded by volume with one chart token at stepped opacity and labelled with its count and share, headline reads for the percentage landing beyond the service box and in the middle third, raw landings drawn as dots at their own coordinates, and a forehand / backhand filter that re-derives every number.
