This example visualizes a knowledge graph of 13 interconnected components, organized into five colored groups representing different functional categories. It shows the relationships and dependencies between entities like “Aggregation,” “Eligibility,” and “Reporting” as directed links with arrowheads. The layout is computed using `d3.forceSimulation` with forces for link distance, charge repulsion, and group-based x-positioning using `d3.forceX`, while the SVG rendering uses D3 v5 to draw nodes and edges. Node colors are assigned via a `d3.scaleOrdinal` based on group membership.
