Organization of addresses (street, houses, apartment, etc.) by graphs in Flask?

Question

Flask

Good afternoon.
It is necessary to organize the database of addresses in graphs, but I don’t even know which side to approach. I read articles, start to understand something, but I'm lost how to organize it in Flask.
Tell me, who did, and / or knows - what kind of database is needed, exactly a graph database, or can everything be saved in regular SQLite, for example?
How should address models look like, and will they be models at all, or documents?
Who is not difficult, please outline an example.
Thank you.

Look at the structure in FIAS there is a flat table of addresses. There is an id parentid level. There are 14 levels in my opinion, that is, by choosing id you can build a complete structure from house to street further to the city, region and region
