a. What graphical methods could you use to display these data?
b. Before you draw your graphs, what trends do you see in each of the variables displayed?
c. Use a line chart to display the number of personnel deployed over this 51-day period.
d. Use a bar graph to display the percentage of federal Gulf fishing areas closed.
