A planar straight line embedding of a graph can be made in the Wolfram Language using PlanarGraph [ g ]. There are a number of efficient algorithms for planarity testing, most of which are based on the algorithm of Auslander ... WebTake a look at the following graphs −. Graph I has 3 vertices with 3 edges which is forming a cycle ‘ab-bc-ca’. Graph II has 4 vertices with 4 edges which is forming a cycle ‘pq-qs-sr-rp’. Graph III has 5 vertices with 5 edges which is forming a cycle ‘ik-km-ml-lj-ji’. Hence all the given graphs are cycle graphs. design your own floor plans
