如何在plotly.py的sunburst图中包装文本？

import plotly.graph_objects as go

labels = ['A', 'B', 'C', 'D']
parents = ['', '', '', '']
values = [10, 20, 15, 5]

layout = go.Layout(
    title='Sunburst Chart',
    margin=dict(t=30, l=0, r=0, b=0)
)

fig = go.Figure(go.Sunburst(
    labels=labels,
    parents=parents,
    values=values,
    textinfo='label+percent entry'
))

fig.update_layout(layout)

fig.show()
