Seasonality Chart

This visual implements the common use-case of charting time-series data on a seasonal basis. It handles the rendering of a seasonal “range” so that users can observe the evolution of typical patterns and identify potential outliers. The visual is aimed at anyone working with time-series data (e.g. commodities) that wants to spend less time on rolling their own solution with the default PowerBI charts, and more on time on getting reports published, fast.
