The Flutter pyramid chart is the form of a triangle with lines dividing it into sections, each section with a different width. Depending on the Y coordinates, this width indicates a level of hierarchy among other categories.
The pyramid chart supports two types of visualization mode, linear and surface. The Y value is represented by the height of the rectangle in linear mode and area of the rectangle in surface mode.
The segments in the pyramid chart can be separated by gaps to highlight the levels in the hierarchy.
Explode a single segment in the pyramid chart to differentiate it from others.
