How to Make a Scatter Plot in Python With plt.scatter()

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 size, color, shape, and transparency are controlled by the s, c, marker, and alpha parameters.
• plt.scatter() enables per-point customization like variable size or color, while plt.plot() with marker arguments runs faster for basic plots.
• A single scatter plot can
