 Using the deferred API, we can check which streets are within `d=10` meters of distance.

-In the previous query, `streets` and `broad_station` are different tables. We use [`to_array()`](../../reference/expression-tables.qmd#ibis.expr.types.relations.Table.to_array) to generate a
-scalar subquery from a table with a single column (whose shape is scalar).

 To visualize the findings, we will convert the tables to GeoPandas DataFrames.
