Tell us what’s happening:
The tooltip tests do not pass when the tooltip is added using the d3 element - append(title) - can tooltip not be added this way?
Your code so far

No, but yours appear to be correct if they did work. You can search the forums for more details, but you should try a div.
You can read about title elements in the standard here. Since they are handled at the discretion of the user-agent and there seems to be a non-configurable transition time, they are not able to be made to work for these tests. They are also required to have display: none set in the user-agent stylesheet with highest priority and I see nothing indicating that that is changed if the user-agent renders the tooltip. So the tests can’t seem them if you use a title element.
Thanks for the response. But, if this not a standard, as previous posts have mentioned, the course should certainly add that information. I see lot of people write the code with the append(title) feature.
The title tag is a way to add extra information like in a tooltip. The W3 standard I linked to is quite explicit in that browsers may render it and probably should render it as a tool tip if they do. Which means it’s not required to be rendered, and hence not suitable to purpose for these tests. So you have to find another way; no course can cover everything.
