An adjacency matrix displays 16 nodes from the soc-tribes dataset as a symmetric grid, where hot pink cells indicate connections and white cells represent absent links. The visualization uses D3 v7 with SVG rendering, employing `d3.scaleBand` for axis positioning and `d3.csv` for data loading. Interactive tooltips highlight rows and columns on mouseover, while the matrix symmetrizes directed links by mapping both directions into a shared `Map` structure.
