As a moderation note:
I have changed the title from " Drawing in Typst" to " How can I draw geometric constructions, sets, etc.?".
The question guidelines recommend this:
Good titles are questions you would ask your friend about Typst.
You already put this question in the body of your original post, it’s a good title that will make it easier for people to find this question in the future.
Also remember to mark the answer that helped you resolve your problem as a Solution using the
