Visualizing data is a core part of analysis, and Python’s most popular plotting library is Matplotlib. To make a scatter plot, you reach for plt.scatter() from Matplotlib’s pyplot submodule, conventionally aliased as plt. You’ll use it to build both simple two-variable charts and richly customized plots that encode several variables at once. By the end of this tutorial, you’ll understand that: A scatter plot is created by calling plt.scatter() with two array-like sequences for the x and y values. Marker […]
