This adjacency matrix visualizes connections within the hi-tech network dataset from networkrepository.com, with each cell representing a directed link between source and target nodes. The SVG rendering uses D3 v7 with linear scales for both axes, positioning 36 numbered nodes along the top and left edges. Users can hover over individual cells to reveal the specific node value, though the interaction may be slow with larger datasets. The implementation applies axis generators and CSV parsing via d3.csv, building the matrix from the provided hi-tech.csv edge list.
