title: Work with Data in D3
---
![:triangular_flag_on_post:](https://forum.freecodecamp.com/images/emoji/emoji_one/triangular_flag_on_post.png?v=3 ":triangular_flag_on_post:") Remember to use <a>**`Read-Search-Ask`**</a> if you get stuck. Try to pair program ![:busts_in_silhouette:](https://forum.freecodecamp.com/images/emoji/emoji_one/busts_in_silhouette.png?v=3 ":busts_in_silhouette:") and write your own code ![:pencil:](https://forum.freecodecamp.com/images/emoji/emoji_one/pencil.png?v=3 ":pencil:")
### Problem Explanation:
We need to make `h2` element as much as the number of values in `dataset` with a text `New Title`, using the `data()`, `enter()` functions.
## ![:speech_balloon:](https://forum.freecodecamp.com/images/emoji/emoji_one/speech_balloon.png?v=3 ":speech_balloon:") Hint: 1
* You will need to select the `body` node, then select all `h2` elements.

## ![:speech_balloon:](https://forum.freecodecamp.com/images/emoji/emoji_one/speech_balloon.png?v=3 ":speech_balloon:") Hint: 2
* You will need to D3 create and append an h2tag using `append()` for each item in the datasetarray using `data()` and `enter()`.

## ![:speech_balloon:](https://forum.freecodecamp.com/images/emoji/emoji_one/speech_balloon.png?v=3 ":speech_balloon:") Hint: 3
* The text in the `h2` should say `New Title` by `text()` function.

**Solution ahead!**
## ![:beginner:](https://forum.freecodecamp.com/images/emoji/emoji_one/beginner.png?v=3 ":beginner:") Basic Code Solution:
```javascript
<body>
<script>
const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];
// Add your code below this line
d3.select("body").selectAll("h2")
.data(dataset)
.enter()
.append("h2")
.text("New Title");
// Add your code above this line
</script>
</body>
```
