How to show rows without data

[djouallah]

using this model, how to show that Tunisia has no Qty ?

https://github.com/djouallah/malloy/blob/main/starschema.malloy

Query: by_Vendor_Continent is {
              group_by: dim_color.Vendor
              group_by : dim_state.continent
              aggregate: Quantity

my understanding Malloy support only left join, so only rows in the fact table will be shown ?
