Does anybody knows whether tikz is the best way to do that?

that should be fairly easy in TikZ. What have you tried up until now? – zeroth Sep 4 '12 at 18:05

This should be all the techniques you need:




\node[draw] (t1) at (0,0) {Twin 1};
\node[draw,circle] (a1) at (-4,1) {A};
\node[draw,circle] (b1) at (2,2) {B};
\draw (a1) -- node[fill=white] {0.42} (t1);
\draw (b1) -- node[fill=white] {0.23} (t1);
\draw[latex-latex] (a1) to[out=45,in=135] node[fill=white] {0.69} (b1);
