Air pollution levels in China are among the most dangerous in the world. Partnered with CSIS, Seven Mile Media produced a data visualization to provide deeper insight into this potentially lethal issue.

Interacting with the controls allows the user to animate the chart, visualizing data from different cities and years.
We used the AmCharts library with a custom designed heat map to display both sets of data simultaneously
