A heatmap (aka ``heatmap()``) is a plot of rectangular data as a color-encoded matrix. As parameter, it takes a 2D dataset. That dataset can be coerced into an ``ndarray``.

This is a great way to visualize data because it can show the relation between variabels including time. For instance, the number of fligths through the years.

In this section, we will perform preparing tasks for the work!

In this section, we will study plots used for data distributions!

It is time to say 'hello' to categorical plot types!

Colorful matrix plots are waiting for you!

These fantastic plots consist of other plots. Let's start this section!

Let's learn plots that are used for regression models!
