my useD3 hook

Remember when we talked about D3 blackbox rendering? I built a hook for that so you don't have to mess around with HOCs anymore :)

Read the full docs at d3blackbox.com

It works as a combination of useRef and useEffect. Hooks into component re-renders, gives you control of the anchor element, and re-runs your D3 render function on every component render.

You use it like this:

import { useD3 } from "d3blackbox";
function renderSomeD3(anchor) {
    d3.select(anchor);
    // ...
}

const MyD3Component = ({ x, y }) => {
    const refAnchor = useD3(anchor => renderSomeD3(anchor));
    return <g ref={refAnchor} transform={`translate(${x}, ${y})`} />;
};

You'll see how this works in more detail when we refactor the big example to hooks. We'll use useD3 to build axes.
