A graph is drawn considering the edges like springs and the nodes like masses.
the key controls are:
't' - toggle trail rendering
'b' - toggle masses rendering
'+' - add masses
any other key to switch between random generation and fully connected graph.
click with the mouse to have some fun.
in RANDOM mode every mass increase as new masses are created and connected with it.
in GRAPH mode every node has the same mass to let the algorithm converge to a beautiful star shape.
