This example displays a directed knowledge graph of robot components, organizing nodes into five color-coded teams and showing various connections between them. The visualization uses d3.forceSimulation to position the nodes and SVG lines with arrowhead markers to represent the directed links between components. The dataset includes 13 nodes with metadata such as runtime and category, while the links are grouped into three distinct relationship types including "Next", "Go to", and "This way". The graph uses an ordinal color scale with custom hex values and a subgraph area to display additional information.
