+## D3 Block-a-Day: Day 22, January, 22th 2017
+
+New Year's Resolution for 2017: Make a D3 Block a day to teach myself D3. This is Number 22. This example
+reduces the size of the [January 20th baseball wins scatter plot](https://github.com/dbetebenner/D3_01202017).
+Like previously, the correlation is supplied in the data set which is JSON.
