The Bucky Ball provides an elegant example of a graph, the connectivity of the Buckminster Fuller geodesic dome.We are also demonstrating publishing this blog with the Live Editor and running animations in MATLAB Online. You should see two buttons at the end of the post. One button downloads the live script so that you can run the animation on your own computer. The other button runs the script on a MathWorks server and displays the results in your browser.BuckyThe statement B = bucky; creates a sparse 60-by-60 matrix, the adjacency matrix of the connectivity graph for a geodesic dome, a soccer ball, a carbon-60 molecule or a truncated icosahedron. These objects all have 32 faces; 12 of them are pentagons and 20 are hexagons. SpyOne view of this matrix is its spy plot, which shows the logical structure of nodes and edges. spy(B)GraphTo get other views, use the MATLAB graph object. The statement G = graph(B);makes a graph. By itself, a graph does not have any geometric
