/**
 * Animates a bar label from the start of the axis (x-axis for vertical layout, y-axis for horizontal layout) to the
 * center of the bar it belongs to.
 * The label is horizontally centered within the bar when the layout is vertical, and vertically centered for laid out
 * horizontally.
 *
 * The props object also accepts a `ref` which will be merged with the ref returned from this hook. This means you can
 * pass the ref returned by this hook to the `path` element and the `ref` provided as argument will also be called.
