Sorry, but you either have no stories or none are selected somehow.
If the problem persists, check the browser console, or the terminal you've run Storybook from.
This isn't really part of the api, it's just used to demonstrate that the Donut is able to adapt in real time to react state changes (through the segments
property), as well as automatically scale past 100 percent, should the percentages of all segments add up to more than 100.
Since the Donut itself is only visual to represent % share of allocation, one way to make this data accessible is to add screen-reader text inside assistive texts used to label the individual Donut segments.
