This network graph visualizes relationships among demographic attributes and screening categories related to ASD traits. The force-directed layout uses `d3.forceSimulation` with `forceLink` and `forceManyBody` to position nodes, while SVG circles and text labels render the connected categories. Nodes are color-coded by group (blue, red, green, purple, orange), and links connect parent categories like Age, Ethnicity, and Gender to specific values such as age ranges or ethnic groups. The graph includes both hierarchical connections and cross-links between categories, revealing potential associations in the dataset.
