Network graph
This interactive network graph visualizes the relationships between features related to cardiovascular disease, with nodes colored by category (Demographics, Lifestyle, Health Indicators, Outcome) and the target 'cardio' node emphasized. It is built with D3 v5, using `d3.forceSimulation` for physics-based layout, including linkage, many-body repulsion, centering, and collision handling. Node size, edge thickness, and a legend clarify feature importance and connections, while tooltips provide value descriptions and drag functionality enables exploration.
