This interactive network graph visualizes the hierarchical relationships among major tech giants (AAPL, MSFT, META, GOOGL, AMZN) across yearly financial metrics (Open, High, Low, Close, Volume) from 2019 to 2023. Using d3.forceSimulation for physics-based node positioning, the SVG rendering features animated links whose widths scale with connection weight. Hovering over nodes triggers a tooltip display, and node colors reflect group assignments via a categorical color scale. The implementation relies on D3 v7's force-directed layout and event handling to create an explorable data hierarchy.
