Serve Miss Map
A four-state tennis fault map in hand-rolled SVG — both service boxes with a net band on the front edge, and net / wide / long miss channels shaded by count and labelled with count plus share, first and second serves side by side.
Return Depth
A four-state return-of-serve chart — returns grouped into depth bands laid out to real court metres, one bar per serve answered, the points-won rate overlaid on a second axis, and a verdict on whether depth converts.
