This example presents a hierarchical organizational tree, showing the relationships among roles from CEO down to individual contributors. It uses d3.hierarchy to structure the data, d3.tree for layout, and d3.linkHorizontal for drawing the curved links. The SVG-based visualization colors nodes by their depth in the tree, with the CEO in green, direct reports in yellow, and lower-level employees in orange, while text labels are positioned based on whether a node has children.
