I was asked in thread 139691 to open a new question - so here we go:
I need to create dependency graphs between characters in LaTex.
As the output shall be processed via "pdflatex" later on, I opted for "TikZ" being said to be compatible with "pdflatex". As "TikZ" itself seems to be to "a science unto itself", I tried out "TikZ-dependency" like depicted in thread 139691.
Nevertheless, I was unable to achieve with "TikZ-dependency" what I want (cf. example drawn in Freeoffice below).
Additionally, one has to bear in mind that there might be more complex examples than the one shown, where alliterations resp. assonances intersect, so that a second row of annotation boxes "Alliteration" resp. "Assonance" with arrows pointing to characters would be needed (like in the examples shown in the package documentation of "tikz-dependency"). However the arrows of the second row's annotations should of course not cross the first row of annotation boxes in front, but in the background behind.
I would be glad if anyone could give me a manageable solution to this challenge. Manageable is meant in terms of simple applicability to a large number of examples.
