D3 Bar Chart Tooltip Not Showing

I’m having problems with the tooltip. When I use the svg title component as taught in the curriculum, I can see it and it works fine, but the tests are not passed. So I replaced it with a mouseover event on a div instead, and while it does pass the tests, I cannot actually see it in my codepen. Why can’t I see it? Codepen here: https://codepen.io/catmother/pen/xxGPXmK Thanks!

The problem was I was using the attr property instead of style to set the left and top of my tooltip. :smile:
