How to create Grouped box plot in Plotly?

import plotly.graph_objects as go


fig = go.Figure()

# Defining x axis
x = ['a', 'a', 'a', 'b', 'b', 'b']

fig.add_trace(go.Box(

    # defining y axis in corresponding
    # to x-axis
    y=[1, 2, 6, 4, 5, 6],
    x=x,
    name='A',
    marker_color='green'
))

fig.add_trace(go.Box(
    y=[2, 3, 4, 1, 2, 6],
    x=x,
    name='B',
    marker_color='yellow'
))

fig.add_trace(go.Box(
    y=[2, 5, 6, 7, 8, 1],
    x=x,
    name='C',
    marker_color='blue'
))

fig.update_layout(

    # group together boxes of the different
    # traces for each value of x
    boxmode='group'
)
fig.show()
