This interactive visualization displays a hierarchical tree of SPDX software package data, showing the structure of a PowerShell package with its associated files and checksums. Users can click on nodes to expand or collapse branches, with a smooth animated transition that adjusts the tree layout accordingly. The visualization uses D3.js v5 with a custom tree layout algorithm, linkHorizontal connectors for the edges, and a zoom feature that responds to user interaction. The animated transitions between states are implemented using D3's transition system with adjustable durations based on modifier keys.
