This visualization displays a hierarchical tree of muscle car models organized by their manufacturers, with nodes representing brands like Ford and Dodge and their respective car models such as Mustang and Charger. The tree uses color-coded nodes based on hierarchy depth and includes interactive features like clickable nodes and zooming via d3.behavior.zoom. Built with D3.js v3, it renders the structure as an animated SVG, pulling data from a JSON file and styling nodes with rect elements and tooltips.
