Hi Rainer, One option is to use svg graphics, which are supported in latex (via the svg package from CTAN) and in HTML (on almost all modern browsers: <http://caniuse.com/#feat=svg>). The svg latex package supports compiling with pdflatex out of the box and lualatex with a little hackery; xelatex is not supported (you also need to install inkscape and compile with a flag that allows latex code to execute shell commands).
Otherwise, you might be looking for something like this worg page: <http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html#sec-4-3>. And also search “by-backend” in the mailing list archives for other relevant examples. Hope this is helpful, -- Aaron Ecay
