Matplotlib

Matplotlib is the grandfather of Python plotting. It is verbose but provides infinite control.

When to Use

• Publication-Quality Scientific Plotting: Generating exact, reproducible figures for academic papers, documentation, and reports.
• Fine-Grained Custom Visualizations: Complete control over every pixel, tick, axis spine, legend, and colorbar.
• Headless Server-Side Chart Rendering: Generating PNG, SVG, and PDF visualizations in backend microservices without GUI displays.
• Subplot Grid Layouts: Assembling multi-panel visual figure grids with GridSpec.

Quick Start
