D3 help with heat map

This project has been real challenging for me and I’ve been stuck trying to pass test #9 for too long now. If someone please help and or give me hints to solve I would greatly appreciate it.

See the Pen D3 Heat Map by Kristian (@Kristians) on CodePen.

I’m stuck on both test #9 & #10. How did you pass #10?

Guys just don’t worry about it. The FCC test are seemingly useless and your heatmap is aligned on the x-axis for me.
