US county map with bubbles
CDP Data Visualization Map visual lets you plot measurements, as bubbles, over US County regions. Bubble maps display up to two measurements simultaneously: as the color of the bubble, and as the relative size of the bubble.
A county map of the United States shows a comparison of measurement values across US States.
The following steps extend the work completed in State map with bubbles and
demonstrate how to create a map visual on the dataset US County Populations
[data source samples.us_counties
]. This produces a map with bubble marks
that correspond to the total population of each county.
