I found this question which is extremely cool and amazing
How to plot Venn diagrams with Mathematica?
which also helped me in plotting and creating Venn Diagrams.
But there is something that is missing, and it's: "How to write something inside the diagrams?"
For example, if I wanted to write a text inside the coloured zones in the figure below, how shall I do?
Mathematica code used: the one in the accepted answer given in the linked question.
Venn Diagram:
VennDiagram2[3,
Subscript[A, 1] && Subscript[A, 2] && Subscript[A, 3] ||
Subscript[A, 2]]
Let's for example insert RED in the bigger zone, and GREEN, VIOLET, BLUE, BLACK; WHITE and so on in the other ones..


Epilog. You might incorporate it in theGraphics[]command theVennDiagram[]function. – Jagra Nov 21 '16 at 18:47Showto compose the Venn diagram with any other graphics. InGraphicsyou can useTextto draw text at the desired locations, which you can get by right-clicking in the Venn diagram and choosing "Get Coordinates". – C. E. Jan 21 '17 at 11:37
