D3 lets you label a graph element, such as a bar, using the SVG <code>text</code> element.
Like the <code>rect</code> element, a <code>text</code> element needs to have <code>x</code> and <code>y</code> attributes, to place it on the SVG canvas. It also needs to access the data to display those values.
D3 gives you a high level of control over how you label your bars.

## Instructions
<sectionid='instructions'>
The code in the editor already binds the data to each new <code>text</code> element. First, append <code>text</code> nodes to the <code>svg</code>. Next, add attributes for the <code>x</code> and <code>y</code> coordinates. They should be calculated the same way as the <code>rect</code> ones, except the <code>y</code> value for the <code>text</code> should make the label sit 3 units higher than the bar. Finally, use the D3 <code>text()</code> method to set the label equal to the data point value.
<strong>Note</strong><br>For the label to sit higher than the bar, decide if the <code>y</code> value for the <code>text</code> should be 3 greater or 3 less than the <code>y</code> value for the bar.

## Tests

```yml
tests:
- text: The first <code>text</code> element should have a label of 12 and a <code>y</code> value of 61.
