This was a larger project for me, not in creating this viz, but in getting the data. I scraped every single transcript for house committee meetings since 1999. If you want an example of what the transcript looks like - https://www.congress.gov/event/107th-congress/house-event/LC18054/text. Let me know if you want me to share the database with anyone, but its quite large. No surprises here that the use of AI has increased since ~2018/19.
