This fork of the World Countries Tree uses D3 v5 to visualize a hierarchical "Form Team" dataset from a JSON file as a horizontal tree diagram. The SVG rendering places team member source categories and options as nodes with slateblue rounded rectangles. Users can pan and zoom the entire visualization via d3.zoom, while d3.hierarchy and d3.tree compute the layout, and d3.linkHorizontal draws the connecting paths. Clicking any node triggers an alert displaying its name, and the code relies on foreignObject for HTML text styling within SVG.
