To be honest, when creating charts for reports, the most time-consuming part isn't choosing colors or adjusting titles, but rather "putting several beautiful charts together so they don't look awkward."

Matplotlib's built-in subplot functionality is good, but it mostly involves manual layout coding. Seaborn and plotnine have some beautiful charts that aren't treated as matplotlib subplots at all, resulting in manual adjustments of legends, alignment, and spacing that take forever.

The emergence of patchworklib aims to make this simple: like playing with puzzle pieces, use "|" and "/" to piece charts together with automatic alignment and packaging. Inspired by R's patchwork, it provides a similar but more Python/Matplotlib-friendly implementation.
