When and how the label text of the pie chart appears.

[Wdingding]

Original way: Pie chart and label text appear at the same time use the mask.
Change plan: Because the new pie chart animation will be modified like this Issues 12553 [https://github.com//issues/12553]. The color blocks of several partitions come out from the starting point at the beginning. All move forward and expand, and at the same time, a single small block expands at the same time.

So how does the label text can draw better?

1. The label text is the same as before, and the effect of using the mask appears in sequence.
   ——It is difficult to be consistent with the pie chart animation.
2. After drawing the pie chart, all the label text fades out together.
   ——Drawing label text needs to add delay, which will increase the overall animation time.
3. The label text and the pie chart rotate clockwise and appear together.
   ——There are too many moving elements on the screen, which will interfere with the animation of the pie chart.

Choose one, or is there a better way?
