Review Comment:
   This looks like it is substantially based on the duckdb implementation: 
https://github.com/duckdb/duckdb/pull/1046/files#diff-d1323eac8a19eb719b259e964df5e9248fb17bf3872f4ea0776566dd2a62ab4b
   
   I think we should at least credit where it came from
   
   I also wonder if we should use the latest version: 
   
https://github.com/duckdb/duckdb/blob/main/src/common/tree_renderer/text_tree_renderer.cpp
