This visualization shows a social network from the Game of Thrones universe as an adjacency matrix. Each row and column represents a character, with cell color indicating shared group membership and opacity reflecting the strength of the connection between two characters. The matrix is built using `d3.json` to load the data and `d3.scaleBand` for positioning. A dropdown menu allows users to reorder the matrix based on appearance, zone, or influence, with the layout updating accordingly. The visualization is rendered as SVG with animated transitions, using D3 v7.
