## Create a Bar for Each Data Point in the Set

This is a stub. <a href='https://github.com/freecodecamp/guides/tree/master/src/pages/certifications/data-visualization/data-visualization-with-d3/create-a-bar-for-each-data-point-in-the-set/index.md' target='_blank' rel='nofollow'>Help our community expand it</a>.
To complete this challenge, you must make use of D3's **.data()**, **.enter()**, and **.append()** methods.

<a href='https://github.com/freecodecamp/guides/blob/master/README.md' target='_blank' rel='nofollow'>This quick style guide will help ensure your pull request gets accepted</a>.
## Hint 1

<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
As with the previous challenges, make use of D3's .data() method, passing **dataset** as an argument.

## Hint 2

Ensure that you follow using .data(arg) with .enter()

## Hint 3

Finally, to create and add the **rect** shape, make use of the .append() method, passing "rect" as an argument. Ensure that you enclose "rect" in quotation marks.

## Solution (!!Spoiler Alert!!)

```
<body>
<script>
const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];

const w = 500;
const h = 100;

const svg = d3.select("body")
.append("svg")
.attr("width", w)
.attr("height", h);

svg.selectAll("rect")
// Add your code below this line
.data(dataset)
.enter()
.append("rect")


// Add your code above this line
.attr("x", 0)
.attr("y", 0)
.attr("width", 25)
.attr("height", 100);
</script>
</body>
```
