This interactive visualization displays a hierarchical tree of an SPDX software bill of materials (SBOM), showing package files and their associated checksums. The D3 v5 code uses d3.tree and d3.hierarchy to compute the layout, with nodes colored blue or cyan to distinguish parent from leaf nodes. Users click nodes to collapse or expand branches, with smooth transitions animating the repositioning. Names appear truncated along edges, while hovering over nodes reveals full details in a tooltip. The SVG rendering supports zooming and panning through d3.zoom.
