Venn diagrams vs. Euler diagrams

In Venn diagrams, all areas (subsets) are shown. Areas that contain no elements (empty subsets) are filled with black color.

In Euler diagrams, only areas that contain elements (non-empty subsets) are shown.

If we want to depict all areas, irrespectively of whether they contain elements or not, We should choose to make a Venn diagram.

If we want to avoid depicting areas that contain no elements, and instead focus only on the areas that are non-empty, we should choose to make an Euler diagram.
