Bug Report: Cufflinks Compatibility Issue with Python 3.13

[blu3-bird]

Description

The code in this repository uses cufflinks library which is not compatible with Python 3.13 and newer pandas versions, causing a ValueError when trying to create plots.

Run the plotting code:

df_pivot.iplot(kind='line', xTitle='Years', yTitle='Population', 
               title='Population (1955-2020)')

Error message:

ValueError                                Traceback (most recent call last)
