Which library would you use to create scatter plots and line graphs in Python?

The use of Matplotlib for creating scatter plots and line graphs in Python is well-established due to its versatility and extensive functionality. Matplotlib is a powerful plotting library specifically designed for creating static, interactive, and animated visualizations in Python. With its variety of functions, it allows users to customize their graphs, control visual aspects like colors, sizes, and markers, and generate high-quality plots suitable for presentations and publications.

While other libraries like Pandas provide functionalities for visualization and can create basic plots, they typically rely on Matplotlib for more complex chart types and customizations. Scikit-learn is primarily a machine learning library focused on model building rather than data visualization, and NumPy serves as a numerical processing library that provides support for large, multi-dimensional arrays and matrices, but it does not directly handle plotting. Therefore, for creating detailed and customizable scatter plots and line graphs, Matplotlib is the most appropriate choice.
