Total Cost of Oil Spills in America Since 2010

Interpretation

This is a proportional symbol map and a line chart that are depicting the Total Cost of Oil Spills in America Since 2010. Each point in the map represents an oil spill and the size of each circle corresponds to how much that spill cost to clean up. Similarly, each point on the line chart also represents an oil spill and the height of the point corresponds to how much that spill cost to clean up. When you hover over a point some details on demand appear in the top left corner and the corresponding points are highlighted on both of the charts.

Conclusions

This chart is interesting because you are able to see the difference in cost for different oil spills in across the United States for a six year period. Some intriguing trends that you can see in the chart are a couple considerably large oil spills that happen all over the country. For example, we can see that there was a spill in California in 2015 that cost roughly $142 million yet I don't remember much news coverage regarding this spill. It's also interesting to note that there are rough outlines of the oil pipelines that carry oil across the United States. This means that there are are a considerable amount of spills happening across these pipelines and some of them are extremely expensive.

I gained inspiration from looking at the examples of Mike Bostock, Gord Lea, and Prof. Sophie Engle.

Interpretation

This is a stacked bar chart that depicts the Net Loss Barrels of Oil Per Year Since 2010. Each bar represents a year and the smaller bars represent how many that barrels were lost in each spill.

Conclusions

This chart is intriguing because you are able to see the individual outcome of different oil spills over a six year period. Some intriguing trends that you can see in the chart are a couple considerably large oil spills that happen in 2015. One disturbing insight to take note of is the data contains columns for Unintentional Release Barrels and Intentional Release Barrels and some of the largest spills happened intentionally. I did some research on a few particularly large "intentional" spills and found documentation suggesting that the spills might not have happened intentionally. This calls into question the entire dataset, but, nevertheless, I attempted to process the present the data in a way that mitigated the lie factor as much as possible.
