We remixed the water usage visual as a map (please excuse the upside-down text – we did it just so we could both write at the same time).
It is a floorplan of the home. All water-consuming appliances or food are drawn in blue. Each room is overlaid with a water drop. The water drop would contain the total water usage of that room (by aggregating the counts in the original visual). The area of the water drop is proportional to the water usage in gallons.
