 * See analogous [d3 function](https://github.com/d3/d3-selection#selection_each).

 * Note that this serves triple-duty for [d3 attr](https://github.com/d3/d3-selection#selection_attr)
 * and [d3 style](https://github.com/d3/d3-selection#selection_style) due to strong typing and a lack
 * of CSS, respectively.
