Classed("goo", true); // remove CSS class goo from p element. style("font-size", "10px"); // set font-size style for p to the result of some // calculation. js"; }); These modifier functions work on both single-element and multi-element selection results. When applied to multi-element selections, these modifications will be applied to each and every selected element. We will see them in action in other, more complex recipes that will be covered later in this chapter. When a function is used as a value in these modifier functions, there are actually some built-in parameters passed to these functions to enable data-driven calculation.

Function chaining The next interesting aspect of this particular example is the capability of chaining functions to each other. This is also the predominant function invocation pattern that the D3 library deploys since most of the D3 functions are designed to be chainable to provide a more concise and contextual programming interface.
