## Create a Scatterplot with SVG Circles
This is a stub. <a href='https://github.com/freecodecamp/guides/tree/master/src/pages/certifications/data-visualization/data-visualization-with-d3/create-a-scatterplot-with-svg-circles/index.md' target='_blank' rel='nofollow'>Help our community expand it</a>.
### Hint 1
<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>.
Use the ` data() `, ` enter() `, and ` append() ` methods.
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
### Hint 2
Append circles in the ` append() ` method.
### Solution
Chain the following lines of code in the ` svg.selectAll("circle") ` chain:
```javascript
.data(dataset)
.enter()
.append("circle")
```
The ` svg.selectAll("circle") ` chain should look like:
```javascript
svg.selectAll("circle")
.data(dataset)
.enter()
.append("circle")
```
##### Note
The circles won't be visible because we haven't set their attributes yet. We'll do that in the next challenge.
