    Scagnostics:
    Visual features help us to characterize 2D scatterplots: Visual analytics?
    Scagnostics are computed on on three geometric graphs



    A Stringy shape is a skinny shape with no branches



    Computing Convex: The ratio of the area of the alpha hull and the convex hull
    Scatterplot Matrix vs. Paralell Coordinates:
