This network visualization maps relationships among ten patient records in an embedded health dataset based on cholesterol similarity, connecting individuals whose cholesterol levels differ by less than 30 mg/dL. The force-directed layout spreads nodes using D3.js v7’s `d3.forceSimulation`, combining `forceLink`, `forceManyBody`, `forceCenter`, and `forceCollide` to position nodes and prevent overlap. Link thickness encodes the absolute cholesterol difference between connected patients, while node labels display age, blood pressure, and cholesterol values. The SVG rendering uses distinct styling for network nodes, links, and labels to keep the graph readable.
