Visualize Data with a Bar Chart - Help Please

Hi All,
Doing the project and scratching my head as to why the tooltip tests aren’t passing in my solution?

Here’s my Codepen:

And here’s the element from the Dev Tools:

<rect width="2.2545454545454544" height="300.86168051503756" x="644.2181818181817" y="59.13831948496244" data-date="2014-01-01" data-gdp="16984.3" fill="green" class="bar"><title id="tooltip" data-date="2014-01-01">$16984.3 Billion</title></rect>

Would love some advice or to be pointed in the right direction.
