Makeover Monday, 2017 #25

More Exasol-based data in Makeover Monday week 25. 200 Million+ ozone air quality readings from the EPA and a goal to make over a multi-year air quality tile plot on the EPA website. I spent way too much time exploring the data so only had time for a quick make over in the end and this short blog post. Checkout some of the other participants efforts on twitter or wait for Andy and Eva’s weekly summary to see some really cool visualisations.
