• as go: The alias go is a shorthand to simplify the code when referencing plotly.graph_objects.

2. Data for the Sunburst Chart

labels = ["Root", "Branch 1", "Branch 2", "Leaf 1", "Leaf 2", "Leaf 3"]
parents = ["", "Root", "Root", "Branch 1", "Branch 1", "Branch 2"]
values = [10, 5, 5, 2, 3, 5]

• labels: A list of all the nodes in the hierarchy (categories or parts of the sunburst).
• "Root" is the top-level node.
• "Branch 1" and "Branch 2" are second-level nodes under "Root".
• "Leaf 1", "Leaf 2", and "Leaf 3" are third-level nodes connected to…
