Web UI (wvlet ui)

You can start a web-based query editor by running wvlet ui command. This will start a web server on http://localhost:9090 where you can write and execute Wvlet queries.

For starting the Web UI with a sample TPC-H dataset, run wvlet ui with --tpch option:

$ wvlet ui --tpch

This command will open a web browser for editing Wvlet queries.
