Relationship	Diagram
Two unrelated categories	Two separate, non-touching circles
One category fully inside another	Smaller circle completely inside the larger circle
Partial overlap	Two circles overlapping in a shared region
Three-way relationship	Three overlapping circles (e.g., Doctors, Men, Players)

💡 Example: "Doctors, Men, Players" — some doctors are men, some men are players, some doctors are players → represented as three overlapping circles.

💡 Venn diagrams are the visual tool used to solve Syllogism (next chapter) — practising diagram-drawing here directly improves syllogism accuracy.
