Description

D3 lets you add inline CSS styles on dynamic elements with the style() method. The style() method takes a comma-separated key-value pair as an argument. Here's an example to set the selection's text color to blue: selection.style("color","blue");

Instructions

Add the style() method to the code in the editor to make all the displayed text have a font-family of verdana.

Tests

tests:
  - text: Your <code>h2</code> elements should have a <code>font-family</code> of verdana.
    testString: assert($('h2').css('font-family') == 'verdana');
  - text: Your code should use the <code>style()</code> method.
    testString: assert(code.match(/\.style/g));
