Download historical daily stock price data for a few stocks from the Internet. Write down a purpose statement for creating a visualization to analyze this data. Then, create a good and a bad example of a viz addressing the purpose. The good viz should use the appropriate chart type; the poor viz should use an incorrect chart type. Describe why the different types are good or bad examples of achieving the visualization purpose.
