This visualization displays the administrative hierarchy of Chandrapur District, showing towns and villages as a branching tree structure. The data comes from a JSON file with nested parent-child relationships, and the layout uses the `d3.tree` and `d3.hierarchy` functions to position nodes. Horizontal links are drawn with `d3.linkHorizontal`, while SVG text elements display each location name with font sizes scaled by node depth, and a `d3.zoom` handler enables panning and zooming the entire diagram.
