Thanks for working on this! Unbound expressions deserve more attention in the docs. |

| In Ibis, you can define unbound tables. An unbound table is a table with a | ||
| specified schema but not connected to a data source. You can think of it as an | ||
| empty CSV file with just the header. |

I find the CSV analogy a bit confusing :)

Rephrased slightly. Let me know if it's still confusing?

This is looking good, @chloeh13q ! A few small changes, then we can trigger a docs preview to take a look

This looks good @chloeh13q -- I spotted one more small thing in the docs preview, but otherwise I think this is good to go.

ooooh, ok, this might be something for a followup PR, but it would be really cool to have a second ibis connection that can load in the same parquet data so you can show off executing the same unbound expression (and hammer home the separation of interface from engine) |

@gforsyth Great point! I added another section to demo execution on Polars, but let me know if there's another backend that you think would complete the story better |
