Layout
This interactive circular visualization uses a zoomable bubble layout to display hierarchical data, with circles sized by a `size` value and colored by depth. The visualization presents a root node with a single child "abc" that contains six leaf nodes, each with sub-elements. Users can click any circle to zoom into that hierarchy level, with smooth animated transitions between views. Built with D3 v4, the code applies `d3.pack()` for the circle layout, `d3.hierarchy()` for data structuring, and `d3.interpolateZoom` for camera-like zooming. The SVG rendering includes hover effects on nodes and labels that fade in only for visible parents. Data comes from a local `flare.json` file.
