 This outline is unclear as `B` clearly is a child of `A` but when we move on to `C` the clarity is lost. `C` is not a child of `B` with a higher indentation nor does it have the same indentation as `B`. The only thing that is clear is that the first node with smaller indentation, indicating a parent, is A. Then Mermaid relies on this known truth and compensates for the unclear indentation and selects `A` as a parent of `C` leading till the same diagram with `B` and `C` as siblings.

 # Pie chart diagrams
 
 > A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented. The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801
