This radial icicle tree visualizes a hierarchical government structure, starting with the Government of AB and its agencies. The visualization uses a horizontal link-and-node layout with text labels positioned at each node’s coordinates, rendered as an SVG. It is built with D3 v5, using the `tree`, `stratify`, `linkHorizontal`, and `zoom` APIs to lay out and navigate the hierarchy. Node labels display numeric IDs, and panning/zooming is enabled via the `zoom` event, which applies a transform to the SVG group.
