This visualization presents the playing styles of Gomoku players, projected into a two-dimensional PCA space, and distinguishes between human players and AI opponents. The scatterplot uses Voronoi tessellation to partition the space, with each cell colored according to its associated data point. The code relies on the D3.js library (version 3) to render the SVG, and includes interactive features such as zooming and highlighting specific players by name. A separate radar chart, created with a custom `RadarChart` function, compares three players’ similarity to various AI strategies across multiple axes.
