This is a hierarchical tree diagram of world countries, organized by continent and region, with the root labeled "Fuck." It uses D3.js v5’s `tree()` layout and `linkHorizontal()` generator to render the structure as SVG, with text labels sized inversely to depth. The visualization supports zooming and panning via D3’s `zoom()` behavior, while a custom Playfair Display font and teal strokes style the paths. Data comes from a JSON file, though the dataset appears truncated at Eastern Asia.
