This fork of tree visualizes a job hierarchy using a horizontal tree layout, organizing positions by work type (HOURLY or YEARLY) and location, with leaf nodes representing specific job titles. The rendering uses D3 v7’s `d3.hierarchy` and `d3.tree` layouts, drawing SVG links via `d3.linkHorizontal` and nodes as distinct shapes—circles, rectangles, and diamonds—colored by depth. Node labels are positioned based on whether each node has children, and a legend clarifies the shape-color mapping.
