The image is generated by the randomized algorithm available here. The algorithm randomly selects a number of layers and connections between the layers in the software supply chain of a hypothetical project.
The image is generated by the algorithm available here. It reads a CycloneDX SBOM, extracts the sha-256 checksums of all dependencies in the SBOM. Each checksum is represented as a 'spoke' in the SBOM wheel. Each character in a checksum is mapped onto on element on the 'spoke', it is represented as a square or a line.
