This example demonstrates a tree visualization using the Flare dataset, displayed as a circular layout with labeled nodes and hierarchical branches rendered in SVG. The code uses D3 v5’s `d3.hierarchy` and `d3.tree` to compute node positions, then draws links and circles with `d3.select` and SVG elements. The hierarchical structure shows parent-child relationships across categories like analytics, animate, and physics, with each leaf node’s value represented by its visual placement. The visualization is contained within a fixed 960x500 viewport.
