This example presents a family tree as a zoomable, horizontal node-link diagram. It visualizes hierarchical relationships across multiple generations, with each individual represented as a labeled node and colored links connecting parents to children. The visualization uses D3 v5's `tree` layout and `linkHorizontal` generator to position nodes and draw curved paths, while labels display each family member's name with distinct colors. The SVG scene supports pan and zoom through D3's `zoom` behavior, and the code loads data from a JSON file, using the `hierarchy` function to structure the nested family data.
