Customizing velocity
In our previous recipe, we touched upon force simulation node object and its {x, y} attributes, which determine the location of a node on the layout. In this recipe, we will discuss another interesting aspect of physical motion simulation: velocity. The D3 force layout has a built-in support for velocity simulation, which relies on the {vx, vy} attributes on the node object. Let's see how this can be done in the example described in this recipe.
