— Overall performance is average.

— Bonus goal is completed.

the pieces do not return to the place when the mouse moves quickly outside the block

wrong y axis on 2nd chart

Application works fast and animation is very smooth. Great work!

Small things that can be improved:
1. On mobile device default navigation area is a bit small which is uncomfortable to move (especially the first move from the right)
2. Scroll on mobile device works only if you scroll the area between charts

It is impossible to select less than almost two months on daily graphs

When slow internet

Long touch event is working good, but only on touch devices

Hold tab selects text at button

There are bonus tasks. But the charts can be zoommed only on double click / double tap. Clicking on tooltip doesn't do anything.

Wrong timeline (navigator) for the pie chart

Pie zoomed mode should have range for 7 days, current and 3 before and 3 after days.

Pie zoomed mode should move range by one day. Check telegram video3.

Btw I used same animation :) good luck

Wrong date selected when entering into pie chart from the stacked percentage chart.
Wrong value is displayed in the pie chart, compared to the selected date it has been opened for.

axes labels flicker but all bonus goals completedand beautifull zoom animation, I like it (6,3)

Long touch reveals context menu on iPhone

X axis labels in zoomed mode are not following mockups design

No animation on values change

Scroll bar does not snaps to days or months.
Strange minimal range 1 April - 25 May for example

Confusing controls on desktop. While button is on tooltip, I have to double click. I've spent a minute to figured this out

Zoom out button is clickable during out animation. So I can click it man times and twitch the chart

many fast clicks

Just scrolling can make chart blank

Empty main view after zooming in when move the brush right after clicking the legend

Works fast, but without any animation of chart scaling. So you just draw chart as is at each moment, but smooth changing of scale is required

Selected point changes position discreetly. But moving from point to point must be animated as it showed on video example provided by telegram (see example video #1)

You have an obfuscated code
