Data Visualization Projects - Choropleth Map - County data does not match with the map

Tell us what’s happening:

Hi team,

actually, I already finished the project. However, accidentally found a weird issue → Tooltip is showing up as expected for all counties, but none of the county data actually does match with the projected US map. I couldn’t find the root cause. Wondering what I’m overlooking. Does the order of the data from the JSONs not matching? :thinking:
It appears very hard to determine this though (at least for me)

Here is my pen.

Thanks in advance!

I haven’t done any of these challenges, but don’t the County fips correspond to the Polygon id?

Yes! That was the little detail I seem to be overlooking all the time. Many thanks!
