Example with nested json/dict like data, which has been pre-aggregated and pivoted

df2 = df_from_json(data)
df2 = df2.sort('total', ascending=False)
df2 = df2.head(10)
df2 = pd.melt(df2, id_vars=['abbr', 'name'])

scatter5 = Scatter(
    df2, x='value', y='name', color='variable', title="x='value', y='name', color='variable'",
    xlabel="Medals", ylabel="Top 10 Countries", legend='bottom_right')
show(scatter5)

Use blend operator to "stack" variables

scatter6 = Scatter(flowers, x=blend('petal_length', 'sepal_length', name='length'),
                   y=blend('petal_width', 'sepal_width', name='width'), color='species',
                   title='x=petal_length+sepal_length, y=petal_width+sepal_width, color=species',
                   legend='top_right')
show(scatter6)
