This radial tree visualization displays a hierarchical dataset of countries, organized by regions under a top-level "News" category. The code uses d3.cluster and d3.hierarchy to compute the layout, with SVG paths drawing curved links between parent and child nodes. Leaves and internal nodes are labeled with country and region names, using d3.scaleSqrt to vary font size by depth. The tree supports interactive panning and zooming via d3.zoom, transforming the entire graph group. Data comes from a local data.json file.
