This visualization displays a knowledge graph of computer science topics, using a force-directed layout via `d3.forceSimulation` with forces for links, charge, x, y, and collision. Nodes are colored by group and positioned along vertical axes corresponding to their group value, revealing a taxonomic structure. The SVG rendering includes labeled arrows on links via `marker` elements and text paths for edge labels. The dataset is defined in a separate JavaScript file and loaded as an ES module.
