1. A computer-implemented method, comprising: receiving social media data that includes topic information included in the social media data, sentiment values for at least some of the topic information, and location information correlated with the topic information; receiving user selection of a search term, a search term density value, and a sentiment density value for a particular sentiment value; comparing, for locations identified in the location information, a number of occurrences of the search term to a total volume of social media data received to determine a density of the search term at each of the locations; filtering the social media data to identify a set of locations that meet the user selected search term density value; filtering the set of locations to identify a subset of locations that meet the user selected sentiment density value for the particular sentiment value; and populating a map interface with indicia of the search term such that the search term is visually associated with the subset of locations, the indicia of the search term indicating one or more particular locations where the determined density of the particular sentiment value for the search term meets the user selected density value for the particular sentiment value.
