How to use the application:

Select a county or type a county name into the selection box – or click a county on the map – to display its population pyramid for the selected group and year.  Use the time slider to browse between yearly projections, and click the “play” button to produce an animation.  Click the radio buttons to display population pyramids for non-Hispanic white, non-Hispanic black, and Hispanic populations.

The chart itself is also interactive; hover your cursor over any data series to view a tooltip with its value.  Click and drag to zoom in to specific parts of the chart, and click the legend entries to turn either Male or Female bars on and off.
