Several years ago I was impressed with this post from Gilles Castel, but personally I find Inkscape too much for what I need. I discover ipe a short time ago.

This org package offer the ability to create and modify drawing with IPE, that is obviously a dependency.

I usually export my document with org-latex backend, in order to correctly export svg you must include:

#+LATEX_HEADER: \usepackage[inkscapelatex=false]{svg} 

and then make sure that you have -shell-escape in your org-latex-pdf-process command. Like this:

(setq org-latex-pdf-process
      '("pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
        "pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"))
