Introduction:

The project is to plot two graphs together: Dow Jones Industrial Average and new Covid-19 confirmed cases per day.

User Interface:

• Run the main script.
• Enter the numbers prompted on the screen.
• The graph will appear after that.
• Rerun the main script to get the new graph.

Warn.

• The date includes from 2020-01-22 to 2020-09-02, and any number doesn't fall into the range will cause an error.

Conclusion:

• It is obviously that sometimes increasing confirmed new cases can lower Dow Jones Industrial Average dramatically.
