DataViz Tip #21: Explanatory vs. Exploratory Charts

Sometimes you create charts to tell some specific story or drive a point home. Like in this chart of the stock market performance during 2016 US Presidential election night taken from this CNN article:

This is especially true in print or static digital visualizations.
