Plot.Text.Histogram

Description

Plot Histogram as unicode strings; for terminal plotting. For example, one could plot answers and their frequencies to the question:

"Who's your favorite metal band?"

plot $ Histogram
    { width  = 80
    , height = 24
    , bins   =
        [ ( "Metallica", 78 )
        , ( "Iron Maiden", 61 )
        , ( "Slayer", 16 )
        , ( "Dimmu Borgir", 3 )
        , ( "Ghost", 48 )
        ]
    }
