This interactive adjacency matrix visualizes network connections between U.S. states, with each cell colored by the connected state's degree count. The SVG rendering uses D3 scales and ordinal bands to position rows and columns, while an animation transitions between sort orders (name, count, group) over 2.5 seconds. Hovering highlights the corresponding row and column labels. The data comes from the contiguous-usa.json file, containing 49 nodes and links defining state boundaries.
