After manipulating data structures with NumPy and Pandas, understanding the information within them is the next logical step. Data visualization provides the tools to graphically represent data, making it easier to identify patterns, trends, outliers, and relationships that might be missed in raw tables. This process is fundamental for both exploratory data analysis and for communicating results effectively.

This chapter focuses on two core Python libraries for creating static plots: Matplotlib and Seaborn. You will start with Matplotlib's foundational concepts, learning how to generate common plots like line graphs, bar charts, histograms, and scatter plots. We will cover customizing these plots with labels, titles, colors, and styles, as well as arranging multiple plots within a single figure using subplots.

Next, you will be introduced to Seaborn, a library built upon Matplotlib that offers a higher-level interface specifically designed for creating informative and attractive statistical graphics. You will learn to generate more complex visualizations such as heatmaps, pairplots, and distribution plots with concise code. Finally, we will cover the practical aspect of saving your generated visualizations in various formats suitable for integration into reports and presentations. By the end of this chapter, you will be able to choose appropriate plots for different data types and analysis goals and implement them using Matplotlib and Seaborn.
