TikZ, like pstricks, can make good drawing for LaTeX.  One difference is that using TikZ with pdflatex is good to get PDF output directly while using pstrick, a route of DVI -> Postscript -> PDF is needed.  Inkscape is an Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.  It is possible to export from Inkscape drawings to either TikZ or pstricks codes ready to be included in LaTeX file.

  1. Download and install Inkscape v0.92.5. (Note. The extension does not work with Inkscape v1.x yet.)

  2. Add Inkscape to TikZ exporter extension.
