This interactive tree graph uses D3.js v7 to display a hierarchical breakdown of countries and the resources they are known for, with data loaded from a CSV file. The visualization arranges nodes in a dendrogram layout, using SVG paths to draw curved links between a root node labeled "Earth" and its descendants. Node circles are styled in steel blue, and text labels indicate each country or resource name. The code filters out the root and specific "Earth" connections to focus on meaningful relationships within the dataset.
