@ Shailesh gavathe, you can achieve the same as @vestland showed with plotly.express if you specify it in fig,.update_traces.

data = dict(
    character=["Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"],
    parent=["", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve" ],
    value=[10, 14, 12, 10, 2, 6, 6, 4, 4])

fig = px.sunburst(
    data,
    names='character',
    parents='parent',
    values='value',
)
fig.update_traces(leaf=dict(opacity=1))
