This interactive family tree visualization presents hierarchical relationships as a horizontal dendrogram, with root nodes branching outward to descendants. The tree is rendered as SVG using D3 v5’s `tree()` layout and `linkHorizontal()` path generator, while a `zoom()` behavior enables pan and zoom. Node colors and font sizes vary by depth, with labels drawn from a JSON data file. The React framework manages the component, and CSS applies the Playfair Display font and a white text shadow for readability.
