The mekko chart, or specifically the bar-mekko chart, below shows greenhouse gas emissions for the 5 largest US states.

The width of each column is proportional the state’s population.  The column labels also include the population data.  The height of each segment in a column represents metric tons per capita emitted for each type of greenhouse gas.  Because some the of segments were small, a legend is used.  For cleanliness, the labels for smaller segments were excluded.  In addition, this mekko chart has visible x and y axes.
