This visualization shows a hierarchical tree of Chandrapur District, with the district as the root and expanding to towns like Bramhapuri and Nagbhid, which then branch into their constituent villages. The tree layout uses `d3.tree` and `d3.hierarchy` to calculate node positions, with `d3.linkHorizontal` generating the curved connecting paths. The SVG text labels are sized inversely with depth, using larger fonts for higher-level nodes, and the entire view supports pan and zoom through the `d3.zoom` API. The data comes from a local JSON file that defines the nested district-town-village structure.
