* Add short "D3 in React" section

I know you removed the TODO but I was already trying to fill it in! 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

Radial links

A radial link generator is like the Cartesian link generator except the x and y accessors are replaced with angle and radius accessors. Radial links are positioned relative to the origin; use a transform to change the origin.

linkRadial()

Source · Returns a new link generator with radial tangents. For example, to visualize links in a tree diagram rooted in the center of the display, you might say:

const link = d3.linkRadial()
    .angle((d) => d.x)
    .radius((d) => d.y);

linkRadial.angle(angle)

Source · Equivalent to link.x, except the accessor returns the angle in radians, with 0 at -y (12 oclock).

linkRadial.radius(radius)

Source · Equivalent to link.y, except the accessor returns the radius: the distance from the origin.
