The above plot is a heatmap, which is essentially a 2D histogram. Based on data sorted into bins along both dimensions, resulting in a grid of bins.

If you’ve ever found yourself swimming in an ocean of data, struggling to make sense of the waves of numbers and categories, then you’ve come to the right place. Today, we’re going to talk about a lifesaver in the sea of data: binning, and specifically, how to do it in SQL. Now, you might be thinking, “Binning? What’s that got to do with data?” Well, I’m glad you asked!

In the world of data analysis, SQL reigns supreme. It’s a versatile tool, capable of handling enormous data sets and complex queries with ease. But it’s not just about retrieving data — SQL also has powerful data transformation capabilities, one of which is binning.

But enough of the preamble, let’s dive into what you can expect from this guide:
