This is so awesome! Exactly what I was hoping for when I released the dataset, thank you and nice job.

(And if you'd like to do the same analysis on a larger dataset, please reach out!)

Q,U,V,X,Y,Z are interesting. Not really sure how to read the map though. Does black mean its placed there the most or least?

What a wonderful analysis and visualization! Simple, easy to understand, and providing some insights.

Is black hot or cold? It should probably be red
