1. A method comprising: accessing, by at least one processor from at least one non-transitory computer-readable memory device, a map and a hierarchy of places included in the map, wherein: on the map, places at a same level in the hierarchy are non-overlapping with each other; and on the map, places in a lower level of the hierarchy are bounded by places in a higher level of the hierarchy; accessing, by the at least one processor from the at least one non-transitory computer-readable memory device, quantitative information associated with places in the hierarchy; generating, by the at least one processor based on a received scaling input, graphical data to display the map, the map including a first place at a first level in the hierarchy and at least a threshold number of other places at a second level in the hierarchy; determining, by the at least one processor based on the graphical data to display the map including at least a portion of at least the threshold number of other places at the second level in the hierarchy, to aggregate the quantitative information at the second level in the hierarchy for the threshold number of other places on the map; determining, by the at least one processor based on less available data for the first place on the map that is at the first level in the hierarchy, to aggregate the quantitative information for the first place on the map at the first level in the hierarchy, the second level being lower than the first level and the first place on the map being non-overlapping with the threshold number of other places; aggregating, by the at least one processor, the quantitative information for the first place at the first level based on the determining to aggregate the first place at the first level and for the threshold number of other places at the second level based on the determining to aggregate the threshold number of other places at the second level, the aggregating including independently aggregating the quantitative information associated with the first place at the first level and the threshold number of other places at the second level; and adding, by the at least one processor, to the graphical data to display the map, an indication of the aggregated quantitative information for the first place and for each of the threshold number of other places.
