How do you filter data in a particular plot?

From the documentation, I can see examples of filtering the entire dataset up-front, like in the example: https://uwdata.github.io/mosaic/examples/ in which we provide { where: "Symbol = 'AAPL'" } to filter just for AAPL.

I can't find an example or documentation of loading a larger dataset and showing subsets of it. Like, if in that example, we wanted a page in which we had AAPL, MSFT, and a few other stocks or whatever - in separate plots, how would that work? We probably wouldn't want to set up the executor again?

There's documentation for a query builder, but I don't see how this hooks up to charts: https://uwdata.github.io/mosaic/sql/

There's documentation for methods that seem like they create filtered sub-tables from parquet files: https://uwdata.github.io/mosaic/api/sql/data-loading.html

Is there a way to show a chart of data from a parquet file, but not all the data in the parquet file?

Start with the linked Mosaic examples, query builder documentation, and SQL data-loading API documentation. Determine how filtered subsets from a parquet file connect to charts without setting up the executor again, then document the supported workflow with an example covering multiple filtered plots.
