Web project map?

Question

Cartography

Friends!
I am faced with the task of creating a map (structure, scheme) of a web project, with all the connections and interactions.
Which directories contain which files, which files do what.
Naturally, all this should be with varying degrees of detail.
Whether prompt there is a tool which such scheme can help to draw.
In addition to the tool, perhaps someone knows examples of this kind of circuits, which is much more important.
