Description

Visual and interactivity enhancement to the pie chart which can present additional information to the user and indicate the presence click events.

Issue ticket number and link

Opened to address issue (https://github.com/USEPA/haztrak/issues/733)

To do

The element fires its onAnimationEnd event immediately upon rendering when React strict mode is on. The initial chart animation only works properly when strict mode is turned off. I'm looking for some assistance in solving this problem which doesn't require strict mode to be turned off to see the initial animation in development.
