## Description
Chain the `y` function to the line and pass it a "d function" that returns your `yScale` with `d.followers.twitter` as its argument.
This is similar to how you set the x values. It will use the values of your Twitter followers and your `yScale` to set the y coordinate for each item.
These "d functions" use implicit returns. But if you add curly brackets and a return statement, you can put any JavaScript in there that you want. Including `console.log` statements that can be useful for debugging.
## Instructions
