Check out this Marimekko Chart: https://www.chcf.org/publications/2012/08/data-viz-hcc-national.
It maps US healthcare spending by category (e.g., hospitals, prescription drugs) and by payer ( e.g., private insurance, Medicare, Medicaid).
There are two noteworthy features of the chart:
- the designer uses color to differentiate between public and private spending categories--private spending is in orange shades and public in green.
- the chart is animated tracking spending from 1960 to 2010.
When you combine these two features, it's easy to see how a marimekko chart is a great way to show public spending accounts for a larger percentage in many categories in 2010 when compared to 1960. It's also interesting to note that some categories like prescription drugs and dental services are still mostly privately paid.
The data visualization is a companion to Health Care Costs 101, 2012, part of CHCF's California Health Care Almanac.
