Plot Description:

This generates a map showing USDA NASS weekly statistics. The date you select is rectified back to the latest available date. Historical data is linearly interpolated so that departures can be computed. A complication is that NASS data does not exist before the season has started or ended. In this situation, hopefully the Right-Thing is done!
