Using a lot of inline styles on HTML elements gets hard to manage, even for smaller apps. It's easier to add a class to elements and style that class one time using CSS rules. D3 has the <code>attr()</code> method to add any HTML attribute to an element, including a class name.
The <code>attr()</code> method works the same way that <code>style()</code> does. It takes comma-separated values, and can use a callback function. Here's an example to add a class of "container" to a selection:
<code>selection.attr("class", "container");</code>
Note that the "class" parameter will remain the same whenever you need to add a class and only the "container" parameter will change.
