I encounter an error while doing the tutorial on " The distribution of review ratings"

The code below supposed to plot the histogram but it threw an error message.

df['Rating'].iplot(
    kind='hist',
    xTitle='rating',
    linecolor='black',
    yTitle='count',
    title='Review Rating Distribution')
AttributeError: 'Series' object has no attribute 'iplot'
