I think just making the distinction of modules that touch the DOM and those that don't was super clarifying for me personally when I figured that out. And I always forget the most basic ref pattern (and still might've messed it up here). I don't think we should get into updating or interactivity or whatever, but I think just this much goes a long way toward demystifying (and showing just the most basic best practices). * forgot i made data generic, rm reference to normal distribution * useEffect cleans up after itself Co-authored-by: Mike Bostock <mbostock@gmail.com> * Update getting-started.md --------- Co-authored-by: Mike Bostock <mbostock@gmail.com> * build fixes * index edits --------- Co-authored-by: Toph Tucker <tophtucker@gmail.com>

Center force
The center force translates nodes uniformly so that the mean position of all nodes (the center of mass if all nodes have equal weight) is at the given position ⟨x,y⟩. This force modifies the positions of nodes on each application; it does not modify velocities, as doing so would typically cause the nodes to overshoot and oscillate around the desired center. This force helps keeps nodes in the center of the viewport, and unlike the position forces, it does not distort their relative positions.
forceCenter(x, y)
Source · Creates a new center force with the specified x- and y- coordinates. If x and y are not specified, they default to ⟨0,0⟩.
const center = d3.forceCenter(width / 2, height / 2);
center.x(x)
Source · If x is specified, sets the x-coordinate of the centering position to the specified number and returns this force. If x is not specified, returns the current x-coordinate, which defaults to zero.
center.y(y)
Source · If y is specified, sets the y coordinate of the centering position to the specified number and returns this force. If y is not specified, returns the current y coordinate, which defaults to zero.
center.strength(strength)
Examples · Source · If strength is specified, sets the center force’s strength. A reduced strength of e.g. 0.05 softens the movements on interactive graphs in which new nodes enter or exit the graph. If strength is not specified, returns the force’s current strength, which defaults to 1.
