# --description--
The axes and labels are looking good. Next, you will start to add some of the lines for the data. First is the line for the Twitter data. On a new line, create a new `const` named `twitterLine` and set it equal to `d3.line()`. `line` is a D3 function for creating a line.
# --hints--

```js
assert(/const\s*twitterLine\s*=\s*d3\s*\.\s*line\s*\(\s*\)/g.test(code));
```
