06. Coffee flavours (treemap)

This example uses the pandas and Plotly libraries to create and display an interactive treemap visualization of coffee flavors.

Lets load the dataset.

# Libraries
import plotly.graph_objects as go
import pandas as pd

from plotly.io import show

try:
    __file__
    TERMINAL = True
except:
    TERMINAL = False


# Define URL
URL = 'https://raw.githubusercontent.com/plotly/datasets/96c0bd/sunburst-coffee-flavors-complete.csv'

# Load DataFrame
df = pd.read_csv(URL)

# Show
if TERMINAL:
    print("\nDataFrame:")
    print(df)
df

	ids	labels	parents
