The matrix visualization combines a force-directed graph with an adjacency matrix to explore relationships in a car dataset. Users can click nodes in the force-directed layout or cells in the matrix to highlight corresponding rows and columns, revealing connections. Built with D3 v6, it uses `d3.forceSimulation`, `d3.forceLink`, and `d3.drag` for the interactive network, while the matrix uses `reorder.js` functions like `mat2graph` and `barycenter_order`. Data originates from the UCI Auto MPG dataset.
