This treemap visualizes a hierarchy of movie genres and individual film titles, with color-coded circles representing different generations of the data. The dataset defines a root "MovieGroup" with subcategories like Action, Romantic, and Mythology, each containing specific movies. Built with d3.stratify and d3.tree, the visualization uses SVG elements, including animated paths for connections and circles that transition to a fixed radius. Text labels display the names of each genre and movie, rendered in bold white text over the circles.
