A proportional circle map uses circles of proportional sizes to convey information about data shown in the map. The circles represent numerical values, such as population, occurrence of lightning strikes, or amount of people using alternative transportation. A formula will be used to determine the size of each circle based on the numerical value. Generally bigger circles = a higher number. Here the circles show the Hispanic population of each state, not as a percentage of overall population but as a finite number. In my opinion this map could have been made more informative and readable by making the starting circle size bigger, so that more of a difference could be seen more easily.
