## Description
< section id = 'description' >
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
< section id = '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.
