This example shows a hierarchical tree chart of the top-grossing movies in India and the USA, organized by country, language, and individual film titles. The visualization uses the D3.js v3 `d3.layout.tree` API to position nodes and `d3.svg.diagonal` to draw curved links between parent and child nodes. Rectangles are colored by category—red for country, teal for movie, and lavender for language—with a legend clarifying the color mapping. The tree is rendered as static SVG elements with collapsible node behavior implied through the cursor style, though no interactive update functions are demonstrated.
