Style D3 Labels

src
https://cdnjs.cloudflare.com/ajax/libs/d3/4.3.0/d3.min.js

Description

D3 methods can add styles to the bar labels. The fill attribute sets the color of the text for a text node. The style() method sets CSS rules for other styles, such as "font-family" or "font-size".

Instructions

Set the font-size of the text elements to 25px, and the color of the text to red.

Tests

tests:
  - text: The labels should all have a <code>fill</code> color of red.
    testString: assert($('text').css('fill') == 'rgb(255, 0, 0)', 'The labels should all have a <code>fill</code> color of red.');
  - text: The labels should all have a <code>font-size</code> of 25 pixels.
    testString: assert($('text').css('font-size') == '25px', 'The labels should all have a <code>font-size</code> of 25 pixels.');
