### Is your feature request related to a problem or challenge? The `EXPLAIN` command is a key way to understand what DataFusion has done. However, the output format is not well documented which makes understanding what DataFusion is doing harder The syntax of `EXPLAIN` is documented here: https://datafusion.apache.org/user-guide/sql/explain.html However information on how to interpret what these mean is not available ### Describe the solution you'd like I would like to document how to read an explain plan ### Describe alternatives you've considered I propose adding a new page in the user guide here: <img width="1339" alt="Screenshot 2024-08-20 at 3 22 43 PM" src="https://github.com/user-attachments/assets/ef65b49e-4212-44c1-bcaf-0671d70a868a";> InfluxData has internal documentation about how to read an explain plan that we would like to donate to the public docs (both to help others as well as to have help maintaining them) ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
