ICE 8 - Tree idiom
This interactive tree diagram displays a hierarchical structure of Indian states and their cities, using a collapsible D3.js layout. The visualization shows parent-child relationships through a classic node-and-link design, with nodes styled as circular markers and connected by curved paths. Users can click any node to expand or collapse its children, revealing the geographical breakdown. The chart is built with D3.js version 3.5, using `d3.layout.tree` for positioning, `d3.svg.diagonal` for link paths, and animated transitions via `transition().duration()` to smoothly reposition nodes. The SVG rendering scheme positions vertical depth levels at fixed 180-pixel intervals, with static data embedded directly in the source code.
