This interactive bar chart visualizes energy consumption per person in the U.S. from 2012 to 2021, highlighting the trend alongside climate change context. Built with D3 v5, the visualization uses an axis and bar layout where hovering over a bar triggers a tooltip displaying the exact value. The chart employs a listening rectangle to capture mouse events, with bars colored steel blue that change to green when selected. The tooltip, styled with a light blue background and red span text, provides detailed data points. The visualization is part of a series linked from the main page, connecting energy usage patterns to broader climate discussions.
