This visualization displays a hierarchical tree structure, showing nodes and their relationships as branching links. The data originates from a CSV file, which is processed using `d3.stratify` and `d3.hierarchy`. The tree layout is computed with `d3.tree`, positioning nodes horizontally. Links are drawn as curved paths via `d3.linkHorizontal`, while node labels are rendered as text elements with font sizes scaling by depth. Pan and zoom interactions are enabled through D3's `zoom` behavior, applied to the SVG container.
