By using some simple tools from graph theory, we obtain a characterization ofthe planar convex bodies with Borsuk number equal to two. This result allows togive some examples of planar convex bodies with Borsuk number equal to three.Moreover, we also prove that the unique centrally symmetric planar convexbodies with Borsuk number equal to three are the Euclidean balls.
