A force-directed graph shows the network of connections between a central organization and its associated categories, such as Development, Policy, Media, and Politics. Each main node branches into child nodes with labeled leaf nodes. The visualization uses d3.forceSimulation with forceManyBody, forceLink, and forceCenter to position nodes and links, rendered as SVG circles and lines. Data is defined in a separate data.js file, with node sizes and colors assigned based on hierarchy level.
