# --description--

A scatter plot is another type of visualization. It usually uses circles to map data points, which have two values each. These values tie to the `x` and `y` axes, and are used to position the circle in the visualization.

SVG has a `circle` tag to create the circle shape. It works a lot like the `rect` elements you used for the bar chart.

# --instructions--

Use the `data()`, `enter()`, and `append()` methods to bind `dataset` to new `circle` elements that are appended to the SVG canvas.

**Note:** The circles won't be visible because we haven't set their attributes yet. We'll do that in the next challenge.

# --hints--

Your code should have 10 `circle` elements.

```js
assert($('circle').length == 10);
```
