I saw this project on Hacker News, and I thought I would run it across my Markdown analyzer and found some errors you might want to consider merging. To learn more about why the changes were made, you can review the AI analysis for this README at https://app.gitsense.com/microsoft/data-formulator?doc=1868de2e176c652&highlight=conflicts&other-models=Claude+3.5+Sonnet%2CGPT-4o%2CLlama+3.1+70B

Note, the highlighted text means there were conflicts between models.
