    • There is More to Streamgraphs than Movies: Better Aesthetics via Ordering and Lassoing 

      Bartolomeo, Marco Di; Hu, Yifan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Streamgraphs were popularized in 2008 when The New York Times used them to visualize box office revenues for 7500 movies over 21 years. The aesthetics of a streamgraph is affected by three components: the ordering of the ...
    • Time-Series Plots Integrated in Parallel-Coordinates Displays
