Bar charts are a commonly used data visualisation tool where categorical features are represented by bars of varying lengths/heights. The height or length of the bar corresponds to the value being represented for that category.
Bar charts can easily be created in matplotlib. However, the matplotlib library is often regarded as a library that produces unexciting charts and can be challenging to work with. With perseverance, exploration, and a few extra lines of Python code, we can generate distinctive, aesthetically pleasing and informative figures.
In this video, I show you how you can transform a basic matplotlib bar chart into something that is much more informative and much nicer to look at.
