This network graph visualizes relationships between the top five product categories and top ten countries from a Global Superstore dataset, filtering records to show connections between these nodes. It uses d3.forceSimulation with forceLink, forceManyBody, and forceCenter to position the nodes, with links drawn as lines with arrowhead markers. Nodes are rendered as colored circles in an SVG, with labels and drag interaction enabled. The color scale uses d3.scaleOrdinal with schemeCategory10 to distinguish category nodes from country nodes, and the data is loaded asynchronously via d3.csv from a GitHub repository.
