This is an attempt at creating an example of generating Bullseye or Layered Harvey Ball charts using D3.
For each element in the applications array a new chart is created tracking the status of the configurations, ui, and backend processes completion. Of course this is just some random sample data :)
Children is used to track the status items for each application. Each item in this array should contain a name (string) and a progress (float 0..1) status indicator. The progress value is considered to be in a range of 0 to 1 with 1 being 100% complete and 0 being not even started.
