— Overall performance is average.

— The graphs are slow when scaling on Nexus 5X.
— Filtering the graphs with multiple taps produces lags, #3 and #5 also blink.
— The box with the details about selected points on the graphs is cut in some cases (the attached video).
— Bonus goal isn't completed.

Overall, work looks really good:
- fast and smooth animation
- implemented bonus goal for 2 charts

Bugs
1. If none of chart options is selected would be great to freeze navigation as well
2. Grid animation' behavior doesn't work properly: you can notice that chart' lines disappear from time to time when you move navigation
3. Bonus goal was implemented for 1st and 5th charts only:
Two Y Line chart, Bar chart and Stacked bar chart bonus goals were not implemented
Possibly, on those charts where bonus goal was not implemented would be great to have tooltips to work by hover
4. User is not comfortable to switch Day/Night modes, as well as the button is reachable in the bottom of the page only
5. Paddings could be smaller, not too comfortable to view in desktop resolution
6. Pie chart's tap doesn't work from the first click on Mobile device (iPhone 8, Safari)

time axis blinking

The header and the tooltip texts are not animated

The values displayed in the pie chart are not the same as the values of the selected date for which the pie chart is created

Unfortunately, very low performance :(
