This visualization displays the hierarchical structure of a Software Bill of Materials (SBOM) as a tree layout, showing package files and their associated SHA-1 and SHA-256 checksums. The example loads hierarchical data from a local JSON file and uses d3.json to parse it, though the current implementation only logs the root node’s name to the console. The SVG container size is dynamically set to match the browser window dimensions using document.body dimensions, with the d3 library version 7.6.1 loaded from a CDN.
