1. Create two comparative X-Y plots between Date (X) and 7-Day-Moving-Avg of cases (Y) and deaths (Y). Include x-y lines for California, Florida, New York, and Texas states in the same plot to enable comparison between the states. Label all parts of the plots, especially the axes, the plots themselves, and the legends of colored lines.

2. Create a 2x2 grid of four plots showing 7-Day-Moving-Avg of cases (Y) and deaths (Y) for the states of NY and CA1 . Each individual plot should contain just one x-y line for the respective state. Maintain(Fix) the Y-Axis range constant to enable comparison across the four plots.

3. Create a grid (10 rows x 5 columns) of X-Y plots between Date (X) and 7-Day-Moving-Avg of cases (Y) for 50 states.

4. Make a backup all R-data objects by running save.image() command.

Please help with coding using Rstudio! just need guidance in what to use to create plots
