Note that a graph G can be drawn in several different ways; a graph is planar if there exists at least one way of drawing it in the plane in such a way that no two edges cross each other (see Figure A.2). WebMar 28, 2015 · Using Let d (x, z) = diameter (G) and let y be a center of G (i.e. there exists a vertex v in G such that d (y, v) = radius (G)). Because d (y, v) = radius (G) and d (y, v) = d (v, y), we know that d (v, z) <= radius (G). Then we have that diameter (G) = d (x, z) <= d (y, v) + d (v, z) <= 2*radius (G).
