PocD3
This visualization presents a hierarchical tree of provider categories, such as Architecture and Beauty & Wellness, with nodes labeled by category names and connected by curved links. Built with D3 v5, it uses the `tree` layout and `linkHorizontal` generator to position and draw the graph, while a `zoom` behavior enables panning and scaling. The SVG rendering applies a fixed font size that decreases with node depth, and the data comes from a local JSON file.
