Visualizing the Frequency of Ethanol Spills

2016/12/7 posted in  Portfolio


Using government data tracking chemical spills, the investigative reporting team looked into the increasing frequency of ethanol spills taking place throughout the United States in the past 20 years.

This visualization was challenging to optimize and required reducing the data payload as much as possible in order to have it load more quickly.

The graphics are built using a combination of javascript based data-visualization tools, including d3.js, leaflet.js, heatmaps.js, and metricsgraphics.js.

Admittedly the graphic doesn't load or update as quickly as I'd like, but it was a great exercise in optimizations and opportunity to use new tools to showcase the data in a more enriching and compelling way.

The graphic is available for viewing here. The full story is available for reading here.
