The Oil Economy

This is a visualization of the US Consumption, Gas price, and Oil price trends since 9/11 that I found on I like this one in particular because its very easy to use; just clicking on the 5 buttons on the left will display the corresponding line on the chart. Any line from the chart can be removed by simply clicking the corresponding button again. i also like this visualization because of the high correlation it shows between gas prices, oil prices, and US consumption. As you can see, for the most part of the graph an increase in oil prices means an increase in gas prices, and conversely, a decrease in US consumption. Another feature of this visualization that makes interpretation easy is the "timeline of events" along the top of the chart. hovering the cursor over the green dots reveals specific events that are related to the sudden increase/decrease depicted in the graph.
