The New York Times featured this map the other day showing the states that will gain (green) and lose (yellow) population from the just released 2020 Census data.
What is lacking from the article is a mp showing the current (2010 census) number of seats. I found this Tableau visualization, however the red-blue color scheme makes it difficult to compare the two.

I recolored this map and animated it for better comparison. Some of the shapes between the two cartograms are different but they are similar enough. If I had more time and better skills it would be more readable but it's the best I can do for now.
