    • Sankey Arcs – Visualizingedge weights in path graphsTill Nagel, Erik Duval, Andrew Vande Moere, Kristian Kloeckl and Carlo Ratti
    • Arc diagrams
    • Arc diagrams
    • Arc diagrams
    • Wattenberg, 2002 Steinweber and Koller, 2007Heer et al, 2010 Kerr, 2003Dörk et al, 2011 Wattenberg, 2006
    • Design goals•  Display node strength independent of edge distribution•  Enable comparison of in-weight and out- weight•  Emphasize total weight of a node
    • Spreading out impostsClassic Arcs Sankey Arcs
    • AlgorithmClassic arc diagram Spread out arc bases Reordered head and tail positions
    • Color coding for direction
    • Color coding for direction
    • Limitations•  Consumes more space•  Arc height does not always encode distance
    • Arc height does not always encode distance
    • Consumes more space
    • Consumes more spaceSolution a)Adapt node positioningEqui-distant nodes Equi-sized gaps
    • Consumes more spaceSolution b)Modify visual encoding
    • Scalability Heer et al, 2010 Showing character relationships of the novel Les Misérables.
    • Scalability Reproduction Removed color (encoded character groups). Fixed edge width. Improved label display.
    • Sankey Arcs: Repositioned nodes
    • Sankey Arcs: Adjusted visual mapping
    • Case study: Public transit rides
    • Ridership Visualization
    • Sankey Arcs•  Display edge weights in path graph•  Have less visual obstruction by spreading out arcs•  Allow comparing strength, and in- and out- weights of nodes
