I was doing a Google search a couple of days ago and particularly, I wanted to know what are the options for developers who need to visualize large amounts of data points within applications. To my surprise, I couldn't really find that many solutions, and in fact, most of the results I got were from already many years ago.

But there was one result that grabbed my attention and it was a Reddit post about a user asking how to plot billions of data points? While other users replied saying "try using Power BI or Excel", other users suggested workarounds like using a Pandas DataFrame in the Python environment in order to store and manipulate data. But the user who posted the question didn't want to store and manipulate data, the user wanted to visualize the data!

So, how to visualize billions of data points and why would you do that?
