9. How can I add mathematical equations to my diagrams?
LaTeX is renowned for its mathematical typesetting capabilities. You can add mathematical equations to your diagrams using the standard LaTeX math mode. Simply enclose the equation within `$` or `$$` delimiters, depending on whether you want it to be inline or displayed.

10. Can I customize the style and colors of my diagrams?
Yes, TikZ and PGFPlots offer extensive customization options for styling and coloring your diagrams. You can change the line thickness, add fill colors, adjust font sizes, and much more. The packages provide a wide range of predefined styles, or you can create your own.

11. How can I include my diagrams in other LaTeX documents?
