# --description--
D3 lets you label a graph element, such as a bar, using the SVG `text` element.
Like the `rect` element, a `text` element needs to have `x` and `y` attributes, to place it on the SVG canvas. It also needs to access the data to display those values.
2018-10-04 14:37:37 +01:00
D3 gives you a high level of control over how you label your bars.

# --instructions--
The code in the editor already binds the data to each new `text` element. First, append `text` nodes to the `svg` . Next, add attributes for the `x` and `y` coordinates. They should be calculated the same way as the `rect` ones, except the `y` value for the `text` should make the label sit 3 units higher than the bar. Finally, use the D3 `text()` method to set the label equal to the data point value.
**Note**
For the label to sit higher than the bar, decide if the `y` value for the `text` should be 3 greater or 3 less than the `y` value for the bar.
# --hints--
The first `text` element should have a label of 12 and a `y` value of 61.
```js
assert($('text').eq(0).text() == '12' & & $('text').eq(0).attr('y') == '61');
2018-10-04 14:37:37 +01:00
```

The second `text` element should have a label of 31 and a `y` value of 4.
2018-10-04 14:37:37 +01:00
2020-11-27 19:02:05 +01:00
```js
assert($('text').eq(1).text() == '31' & & $('text').eq(1).attr('y') == '4');
```

The third `text` element should have a label of 22 and a `y` value of 31.
```js
assert($('text').eq(2).text() == '22' & & $('text').eq(2).attr('y') == '31');
```
The fourth `text` element should have a label of 17 and a `y` value of 46.
```js
assert($('text').eq(3).text() == '17' & & $('text').eq(3).attr('y') == '46');
```
The fifth `text` element should have a label of 25 and a `y` value of 22.
```js
assert($('text').eq(4).text() == '25' & & $('text').eq(4).attr('y') == '22');
```
The sixth `text` element should have a label of 18 and a `y` value of 43.
```js
assert($('text').eq(5).text() == '18' & & $('text').eq(5).attr('y') == '43');
```
The seventh `text` element should have a label of 29 and a `y` value of 10.
```js
assert($('text').eq(6).text() == '29' & & $('text').eq(6).attr('y') == '10');
```
The eighth `text` element should have a label of 14 and a `y` value of 55.
```js
assert($('text').eq(7).text() == '14' & & $('text').eq(7).attr('y') == '55');
```
The ninth `text` element should have a label of 9 and a `y` value of 70.
```js
assert($('text').eq(8).text() == '9' & & $('text').eq(8).attr('y') == '70');
```
