This interactive scatterplot visualizes the playing styles of Gomoku players, mapping each player’s PCA-reduced strategy metrics onto a two-dimensional plane. The view is enhanced with a Voronoi overlay that partitions the space around each point, making it easy to compare nearest-neighbor relationships and identify clusters of similar playing styles. Points are colored and labeled by player, with a legend and controls for filtering. The visualization is built with D3 v3, uses SVG for rendering, and includes smooth animated transitions between states, supporting exploration of how players group by style characteristics and rating.
