jenks scale breaks when data array is empty

[davelandry]

Expected Behavior

When passing am empty data array to a visualization that supports no data (like Network or Geomap), the visualization should draw regardless of any properties past to colorScaleConfig.

Current Behavior

When setting .colorScaleConfig({scale: "jenks"}) with an empty array ("linear" works), the visualization never gets past the loading screen.
