/**
 * A wrapper component to access data from the `shared-data` package within MDX
 * files.
 *
 * @param children - How to access the shared data. If it is a render function,
 *                   it takes the data object as a param. If it is a string, it
 *                   takes a path through the data object, formatted like
 *                   `a[0].b.c`. This path should lead to either a renderable
 *                   type or a nested object. If it leads to an object, the
 *                   return value is `${object.value} ${object.unit}`.
