This example combines a force-directed network diagram with an adjacency matrix to visualize Facebook page connections in the food category. The network uses curved paths generated with D3’s `d3.curveBundle` for edge bundling, while `d3.forceSimulation` handles node positioning and dragging. Hovering over a node highlights its corresponding row and column in the matrix, with tooltips showing node names. Both visualizations load CSV data for nodes and edges, rendering in SVG.
