This D3.js v7 visualization displays a hierarchical tree graph of Amazon Prime titles, categorizing movies and TV shows into genres like Comedy, Documentary, Drama, Kids, and Anime. The tree layout uses `d3.tree()` with `d3.hierarchy()` to structure the data, while `d3.linkHorizontal()` draws the connecting links between nodes. Each node renders as circles for categories and rectangles for titles, with text labels, all within an SVG canvas. The dataset comes from a CSV file containing Amazon Prime titles, loaded via `d3.csv()`.
