— Overall performance is poor.

— Short delay on launch.
— The app is slow when scaling.
— Filtering graphs #3 and #5 is also slow.
— 'Total' values is missing for graph #3; Long tap is not implemented.
— Bonus goal is completed, however the pie values are broken:

Doesn't work, uses absolute paths for js and css

I understand there are no bonus tasks and couple of bugs, but I don't think receiving so many down-votes is fair.
Come on, there is even an attempt to implement the pie chart - and the animation on pie chart sectors works better than mine.

Haters gonna hate 🤷‍♂️
I think laggy UX really frustrates people.
After almost any canvas based solution my SVG madness looks too sluggish
