How to Fix the Issue of a Matplotlib Graph Not Displaying in PyCharm

As a beginner in data visualization using Python's Matplotlib, it's not uncommon to run into a snag where your graphs just won't display. If you've found yourself staring at a blank screen in PyCharm after running your plotting code, you're not alone! Let's break down why this happens and how you can get your graphs to show up.
