This visualization shows a bubble chart displaying legal case data, with categories such as Reclamantes, Fases processuais, and Pedidos represented as red circles sized by their count values. Built with React and D3 v4, the example uses d3.pack and d3.hierarchy to compute the circular layout, rendering nodes as SVG groups with appended circles and text labels. Clicking any bubble triggers a simple alert dialog, demonstrating basic interactivity within the packed layout.
