This commit streamlines mood and activity visualization code in
mood/statistics.py for better readability and maintainability. By
consolidating similar code blocks, replacing ' extension calls with
consistent double quotes, and reformatting large data structures for
clarity, we ensure the code is more Pythonic and easier to follow.
Additionally, the alterations in how pie charts and mood statistics are
generated not only maintain functionality but also reduce cognitive load
when navigating the codebase. These changes pave the way for future
enhancements and debugging efforts by making the codebase more
approachable.
