Fork of World Countries Tree
This interactive tree diagram displays a hierarchical organization of world countries, grouped by region under a root node labeled "Potential Advertisement". The visualization uses a horizontal node-link layout, where each country name is rendered as text positioned along the branches. The D3.js library (v5) constructs the tree layout, while custom CSS styles provide a distinct serif font and visual text shadowing. Data is loaded from an external JSON file, and the SVG rendering supports zoom and pan interactions through D3's zoom module.
