LaTeX figures using tikzpicture, pgfplots and overpic
Some examples of how the packages tikz and pgfplots can be used to create fully vectorized graphics directly in the LaTeX document. An example of how a flowchart can be generated in LaTeX is also given. It combines the packages tikz and overpic and shows how to overlay/embed intrinsic LaTeX text onto images created elsewhere.

Escher Illusions in LaTeX
A drawing in TikZ.
The first picture draws an impossible brick, which induces
an optical illusion similar to that triggered by Escher's
impossible cube.
The second picture draws a Penrose triangle, another similar
optical illusion.
