What is the current behavior? (You can also link to an open issue here) currently all gauge arcs start at the min value provided by the results array. #1527

What is the new behavior? we can now display range arcs which will start at an optionally provided startValue and defaults to the min value. The new data format looks like this:

[
  {
    name: 'France',
    value: 36745,
    extra: {
      startValue: 20000,
      code: 'fr'
    }
  }.
  ...
