This network graph visualizes the relationships between cricket-playing countries and match formats (Test, ODI, T20). A force-directed layout positions colored country nodes around gold format nodes, with arrows indicating connections. The D3.js v7 code uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to compute the layout, while SVG circles, lines, and text labels render the result. Data is hardcoded as sample nodes and links.
