Choropleth maps with contextual cumulative frequency legends. A quantile classification is again used to portray the spatial distribution of the percent of low birthweight births by town in Connecticut in the upper-left diagram and to portray the spatial distribution of Lyme disease per 100,000 population by town in Connecticut in the upper-right diagram. A contextual cumulative frequency legend associated with each map is presented beneath the respective map. In these legends, the cumulative frequency curve for the population below the poverty level is given in blue and that for total population is given in green.
