Quadrant chart with two axes naming each corner.
Strategy classics: BCG growth-share matrix, Eisenhower urgency-importance. Two axes form four named quadrants; entities are placed by their position. Often with bubbles for size.
When to use
Positioning frameworks where the two dimensions are conceptual and quadrant naming is the takeaway.
When NOT to use
Both dimensions are continuous quantities with scale (use scatter).
