This Demonstration compares administrative subdivisions (wards) of Madison, Wisconsin with respect to their residential composition. Densely populated areas of a city tend to have more apartment buildings and condominiums than single-family homes. Each column of the chart represents one ward of Madison, colored in proportion to how much living area (as a percent of total) is of a certain kind. Choose a colored button to sort the wards by makeup (this may take a few seconds). Mouseover a column to get data about an individual ward.
