Hi Stefan,

Well, this is what I currently have:

\begin{scope}
\foreach \x/\y/\name/\label/\where in {1.2/1.4/a/{El Paso}/below, 1/3.2/b/Albuquerque
/above, 2.5/3/c/Amarillo/below, 3.8/4/d/Wichita/above, 4.3/3.3/e/Tulsa/45, 5.2/2.8/f/{Little Rock}/right, 4.2/2/g/Dallas/left, 4.8/1/h/Houston ...

I'm looking for a simple way to draw the following picture using tikZ. Namely, I would like to only specify the coordinates of the cities and then to connect them by edges using a \foreach loop. This would be easy if there were no directed edges at this picture.
