The Washington Post has created a series of data visualizations showing the number of oxycodone and hydrocodone pills sold in each United States county between 2006 and 2012. The data, which the Post has also published and comes from the U.S. Drug Enforcement Agency, consists of data about more than 380 million transactions, including the sale of pills to pharmacies.
