Azure Resource Graph is a new capability (currently in preview) which is helping you exploring all your Azure resources.
This is already in use by Azure itself when you use the ‘Search resources, services, and docs’ search box
To start using Azure Resource Graph, search for Resource Graph from the ‘All services’
From there you can launch the Cloud Shell to your query
You can also use Resource Graph directly from your client using either Azure Cli or Azure PowerShell
You can have some query sample here https://docs.microsoft.com/en-us/azure/governance/resource-graph/samples/starter and here https://docs.microsoft.com/en-us/azure/governance/resource-graph/samples/advanced
