— The design doesn't comply with the guidelines.
— The last graph is missing.
— The third graph disappear when scrolling (the attached video).
— Bonus goal is partially implemented, however the overall performance is below average.

The bar charts are with intermediate gaps and without the minimaps

- no chart #5
- white lines between the bars
- no smooth animation between values

Too many notches on the X scale while moving the chart

Untidy header date layout

Wrong off button design

minimap not showed at start, chart disapeared on scrolling

No percentage & pie chart but zoom in line chart look perfect

Zoom of line chart seems to be good, but it is not smooth for some reason. probably too fast, or the easing drives it to mad speed at the end or too many calculations and therefore low fps, or something else. but it is jumpy.

for what reason there are four switch mode buttons

The single column chart in zoomed mode should not have the timeline (navigator) displayed as well as the 'views' button. Instead it needs the tree buttons for the new three lines of the hourly graph

The author did a great job trying to follow the design guidelines, and even implemented several bonus tasks, I don't agree that this work deserves a dislike.
