Chapter 25 MAPS WITH CURVE CHARTS

THE three statistical maps in this chapter, all of which deal with precipitation, demonstrate the value of showing the location of data for geographic regions. While other maps may show that there was rainfall, these maps show the actual amount of precipatation. See "Flow Maps," pages 216-230. Although curve charts have not been discussed up to this point, maps with curve charts are included here in order to keep the map section intact.
