The "Trending at Sundance" widget tracks the real-time popularity of relevant pages on IMDb, and displays those that are currently generating the highest number of pageviews on IMDb.
Each title is ranked according to its share of pageviews among the items displayed. Pageviews for each item are divided by the aggregate number of pageviews generated by the items displayed.
Bubbles are proportionally sized to represent the popularity of each item in the Top 10 relative to the other items. Line graphs represent trends in current pageviews for each item, and do not represent changes in rank among the Top 10.
