Support for tikz is there implicitly in that there is support for
LaTeX.  I use tikz all the time.

Simple example attached.

I do believe others have used asymptote in the past.

#+latex_header: \usepackage{tikz}
* tikz with babel
This example generates a figure using tikz and exports it as raw latex

#+begin_src latex :results latex raw :exports results
  \begin{tikzpicture}
    \node[red!50!black] (a) {A};
    \node (b) [right of=a] {B};
    \draw[->] (a) -- (b);
  \end{tikzpicture}
#+end_src

Alternatively, you can put tikz inline:
#+latex: \tikz \draw[rotate=30] (0,0) ellipse (6pt and 3pt);
which should appear in the middle of the sentence.
