Sometimes it's useful to import several CSV files as tables in one database. For
example, to be able to `JOIN` them in SQL.

In sqliteviz you can not only create a database from a CSV file, but also add
another table from CSV to the existing database.

- Click <img src="./img/add-csv.svg"/> icon in the schema panel on `Workspace`
  page
- Choose a CSV file
- Import it with `CSV import` dialog.
