D3 Scatterplot project: One test failing

Hello! I don’t know what’s wrong, been figuring it out for a while but seems I am not able to do so. Something wrong with the y-axis time decimal precision?

The data-yvalue and its corresponding dot should align with the corresponding point/value on the y-axis.

Thanks

Edit: Also if you have noticed, some non-overlapping circles have darker shade, why is that? :confused:

all the tests pass on mine using chrome browser

That’s weird. I tried the tests on Firefox, Brave and Chrome(Mobile), that one test didn’t pass on all the three browsers.
