Opioid Epidemic

I came across the visualization of US opioid epidemic made by Kieran Healy in his book “Data Visualization: A Practical Introduction” (Link). He has used data through 2014 but in recent years the epidemic has become worse. So I extended the data to 2017 by downloading it from Kaiser Family Foundation’s website. After cleaning up the data, I ended up with an unbalanced panel of 50 states over 1999 to 2017.
