With Joe Biden calling for 100% clean electricity, John Muyskens and Juliet Eilperin for The Washington Post looked at where states are at now in terms of electricity generation.
The variable width bar chart above uses a column for each state. Clean electricity stacks on the top and fossil fuels stack on the bottom, each representing a percentage of total generation. Column width represents total electricity for each state.
It reminds me of the spending graphic by Interactive Things in 2010. I think variable width is about to be a thing again.
