Using the demo: Press play () in the chart below to show how each State's Cigarette Tax ($) and Smoking Ban Coverage (%) changes from 1994 to 2007. The size of the circles corresponds to the percentage of smokers in the state, while the color of the circles corresponds to a "High", "Intermediate", or "Low" degree of the same quantity. The time point shown can be adjusted using the slider at the bottom of this chart.

By 2007, we see that the (blue) "High" Smoking Prevalence states tend toward the low tax and low ban corner of the graph.
We also see that the (yellow) "Low" Smoking Prevalence states are in the middle of the tax range and do not have the highest ban coverage.
