I use R for all my graphs. The tile grid maps are made using the geofacet library along with ggplot2. The package adds the command facet_geo(~ State, grid = "us_state_grid2") which facets the graphs into the map, similar to the facet_wrap command already available in ggplot.
The tile grid maps are impressive. May I ask which tool you used and how you created the maps? Thanks!

Dr. Pfaff, thank you so much for kindly sharing how to make the maps!
