This interactive organizational chart visualizes a company hierarchy using a tree layout, with a rectangular root node for the CEO, green circular nodes for department heads, and orange circles for team members. The code builds the tree using D3.js v7’s `d3.tree()` and `d3.stratify()` APIs, loading data from a CSV file hosted on GitHub Gist. It renders the structure as SVG paths and shapes, with horizontal curved links connecting parent and child nodes based on depth-based styling.
