A force-directed network diagram maps relationships among six cardiovascular disease attributes—gender, smoking, alcohol, cholesterol, glucose, and the cardio target—using D3.js v5 with a custom `d3.forceSimulation` layout. Nodes are grouped by category (Gender, Habits, Health, Target) with a scaleOrdinal color scheme, while link stroke widths encode connection strength. Interactive drag-and-drop repositions nodes, and SVG tooltips describe each attribute’s possible values. The dataset appears to come from a cardiovascular risk factor survey.
