pandas.DataFrame.agg produces a wide data set format incompatible with px.bar. Transposing and updating the indexes to achieve px.bar compatibility is a somewhat involved option. Here is one straightforward alternative, which presents the aggregated data as a stacked bar using plotly.graph_objects....
For example, the keyword argument title places a title on top of the bar chart. Example – Bar Chart of a pandas DataFrame: one column as X-axis and another as Y-axis: import pandas as pd import matplotlib.pyplot as plot # A python dictionary data = {"City":["London", "Paris", ...
