1. One or more non-transitory computer-readable media maintaining instructions executable by one or more processors to perform operations comprising: receiving a selection of a category of content items, the category being one of a plurality of categories; generating an interface including a first representation of a first content item, the first representation being included in a category area of the interface according to the category and the first representation being one of a plurality of representations; receiving, via the interface, an indication of a geographic location; and determining a first value of a metric for the first content item based at least in part on the geographic location; determining a size of the first representation based, as least in part, on the first value of the metric for the first content item relative to values of the metric for others of the content items; determining a size of the category area based, at least in part, on a second value of the metric for the category relative to values of the metric for other categories; generating a graphic effect to indicate a quality of the first value of the metric; receiving, via the interface, a selection of a second representation of the plurality of representations; and presenting in the interface information related to a second content item corresponding to the second representation.
