This interactive D3.js visualization presents a hierarchical tree of AI and data careers, loaded from a CSV file via `d3.csv` and structured with `d3.stratify`. It uses the `d3.tree` layout to position nodes, with horizontal links drawn using `d3.linkHorizontal` and circle markers colored by depth, while leaf nodes are highlighted with purple rectangles. The SVG rendering includes labels aligned based on whether nodes have children, and a chart title is added to the 1100×700 canvas.
