What a pointless bubble chart. If you graph the number of test takers, then of course the states with the largest population (CA, TX) will have the largest bubbles.

This mistake is commonly called making a heatmap of population. Works for nearly any variable - if not per-capita, then you just get a population map. Gun deaths, Methodist ministers, furries, whatever.

If a person random person on the internet looks at it naively, it doesn't provide much information. A person who knows about the US educational system there are anomalies. Compare IL to PA or MD to FL and NY. Use https://en.wikipedia.org/wiki/Us_state_population https://en.wikipedia.org/wiki/Us_state_population as reference.
