A shot chart from a release file

Every shot in the 2025-26 NBA season is one row in a single parquet file, about 4 MB, on a SportsDataverse release. The chart below is drawn from that file in your browser. DuckDB pulls the 4 MB season file once, through the same relay as № 001, and queries it in your browser; d3 draws the hexagons. No server runs a query.

The file is nba_stats_shots/shots_2026.parquet (233,632 shots). It is built by hoopR-nba-stats-data from stats.nba.com and published to the sportsdataverse-data release, refreshed nightly. The chart starts on the Brooklyn Nets, which keeps the first paint small; pick any of the 30 teams, or a player with 50 or more attempts.

The legacy frame

The location columns are x_legacy and y_legacy. "Legacy" is the old stats.nba.com shot-chart frame: tenths of a foot, with the hoop at the origin and y growing toward half court. So the rim is at (0, 0), the baseline sits 5.25 ft behind it (y = -52.5), and the half-court line is at y = 417.5. The corner three runs along x = ±22 ft and meets the 23.75 ft arc at y ≈ 8.95 ft (89.48 tenths). Left is x < 0, as the NBA labels it. The chart flips y for the screen and does nothing else to the numbers.

What the colour means

A hexagon with three shots in it is noise. So each hexagon's field-goal percentage is shrunk toward the selection's overall percentage before it is coloured: (makes + 25·p) / (attempts + 25), where p is the overall rate, as if every hexagon started with 25 attempts at the average. A 1-for-1 corner hexagon reads as average. A hexagon with 60 attempts mostly speaks for itself. Red means above the selection's average, blue below, and hexagon size follows attempts. The tooltip shows the raw makes and attempts, unshrunk.
