In particular embodiments, one or more computer systems query a social graph for social content associated with particular media content, present a content visualization graph for display on a display device, determine a plurality of interesting points of the particular media content based on an amount of social content generated, and provide indications on the content visualization graph of at least some of the determined plurality of interesting points. The content visualization graph provides a visual indication of particular points within the particular media content that the social content was generated. Determining the plurality of interesting points includes determining a respective amount of social content generated for each of a plurality of time periods and selecting, as the plurality of interesting points, a pre-determined number of the plurality of time periods that have the largest amount of generated social content.
