# --description--
Okay, your graph is coming along. All the lines are drawn, but they look a little plain. The next series of code additions will add circles to each point on each line. First is the Twitter line. On a new line, use the `selectAll` function on your `lineGraph` variable and pass it the string `twitter-circles`. It will look like this:
```js
lineGraph.selectAll('twitter-circles')
```
`twitter-circles` don't exist and this selection will be an empty array, but it's needed. For now, you can just think of this string as a reference, similar to a variable name, so you know what elements you are working with.

assert(
/lineGraph\s*\.\s*selectAll\s*\((`|'|")\s*twitter-circles\1\s*\)/g.test(code)
);
