This vertical tree visualization displays hierarchical sales data for the US and UK, with nodes representing countries, salespersons, and chocolate products with their associated values. It uses d3.v7 to render the tree structure as SVG elements, including rectangles, circles, and polygons for different node types. The layout organizes the data from a single root node downward, with lavender-colored links connecting parent and child nodes. A dashed orange tree-box outlines the entire visualization, while bold sans-serif text labels identify each entity within the dataset.
