The diagram you provided shows two classes, G and H, which are within a package named Pckg. Each class has an attribute named 'v' with different visibility and typeindicators. The attribute 'v' in class G has visibility 'private' (denoted by '-'), and in class H, it is 'protected' (denoted by '#'). This suggests that the scope of each 'v' is limited to its respective class. Therefore, when you refer to 'v' within the package, its meaning depends on the context or the namespace from which it's accessed.
