Labels position on big diagram

[AxelBayle]

Hi, we are using the lib to generate all diagrams in our project and it's working perfectly fine. But we have a small issue for our api diagram. Indeed, we have a lot of api route and we wanted to add the label on each edge but somehow the labels are misplacing and we have them at the bottom and not on label ( it's like they are "pushed" by the others edges to the bottom).

Here is the img we get :

And here is the file use to generate it as pdf because it can't put it as .py file ( sorry if not really beautiful we generate it automatically) :

Try using xlabel= instead of label= in each of your Edges .
