This D3.js v5 SVG visualization maps a knowledge graph of robot components, with 13 labeled nodes (e.g., AGGR, CALC, SNAP) colored by team via `d3.scaleOrdinal` and connected by directed, arrow-headed links showing relationships like "Next -->>" and "Go to ->>". Node positions are fixed in the dataset, not force-directed. A subgraph panel and title annotate the layout, while `d3.select` appends the SVG and a marker definition creates the arrowheads.
