Map of the languages and dialects spoken in Italy. The map is merely an approximation of the real status, since it can't be more precise for size and compactness of the informations presented.

It can be easily modified through a vector image editing program, I can suggest Inkscape because it is a free and a very good one.
For minor variations, feel free to do it by yourself. For major variations, please send a message to my talk page. Thank you.
