This example visualizes the steps and secrets defined in a Cloud Build configuration file, mapping them as a directed flow of deployment actions. It shows the sequence of Firebase authentication, npm installation, and function deployment, alongside the encrypted secret environment variables. The visualization uses a custom rendering approach with d3.forceSimulation to layout nodes and links, while reading the YAML structure from the cloudbuild.yml source file. The code references GCP-specific APIs for secret management, though the rendering logic itself is not tied to a specific charting library beyond the force-directed graph.
