A Simple Gravity Model

Explanation: This is a simple demonstration of the gravity model showing the force between objects based on their mass and distance. Orange dots depict an object with mass equivalent to their area and the white line drawn between them shows the force between two objects. Though it is not a perfectly detailed model, the results are quite stunning when there is a large number of objects with distinct clusters.
