This example demonstrates how to generate the coordinate data required to draw Homer Simpson’s head and facial features in Power BI. The code builds an iterator table by stitching together multiple angular ranges, each paired with a category descriptor, using a custom `range` function that leverages `List.Accumulate` to produce evenly spaced steps. The Power Query snippet, written in M, defines a function that takes a category, step count, and start/end angles (expressed in multiples of pi) to create the necessary points. The final `#table` call combines these ranges into a single dataset, illustrating a programmatic approach to constructing parametric shapes for visualization.
