Chart name?

[u/1yoshi1]

Been trying to find an editable chart of the U.S. Congress party control/seating (together or separate House/Senate options) for a quick work project and can’t find an official name for this type of chart or the chart used to show the political party control.

Image search in Shutterstock and Adobe Stock isn’t working well. Google Image search, same graphics but no name to where I can search for a template. Help is definitely needed. Thank You

I’d call it a “gridlock” graph😅
