This visualization shows a hierarchical organization graph with four main nodes connected to smaller child nodes and tiny leaf nodes, each colored by its parent group. The force-directed layout uses d3.forceSimulation with forceManyBody, forceLink, and forceCenter to position the nodes, while SVG circles and lines render the structure. Drag interactions allow users to move nodes, with labels displayed as SVG text elements. The data comes from a JavaScript module defining nodes and links with size and color properties.
