An interactive adjacency matrix built with D3 v6 visualizes character relationships from the Game of Thrones dataset. The SVG rendering displays ten cells in a 5x5 grid, where filled teal squares indicate interactions between pairs of characters. D3 selections bind data to rows and columns using `selectAll` and `enter()`, while `append('rect')` and `append('text')` generate the matrix cells and labels. The title, row, and column annotations use CSS for styling. The simplified network dataset from networkrepository.com appears as an undirected graph, with matrix rows and columns symmetrically mirrored to reflect bidirectional relationships.
