This example visualizes a hierarchical dataset of car types, including sedans, SUVs, and trucks, using an interactive SVG tree layout created with d3.tree. The root node is rendered as a red circle, first-level children as green rectangles, and leaf nodes as blue triangles, with curved links connecting parent and child nodes via cubic bezier paths. D3 v5 hierarchy is used to structure the data, while SVG shapes and text labels display each car model name. The visualization demonstrates a simple, color-coded dendrogram for categorical product categories.
