Seems like a potentially useful tool. Another related approach is https://github.com/GoogleCloudPlatform/terraformer ("reverse Terraform"), which might be better if your end goal is to build Terraform scripts for existing infra.

However I like the idea of using these visualizations to grok or monitor infra; say as a Platform or Security engineering team, you might want to keep an eye on specific classes of resource like storage buckets, load balancers, etc.
