Visualizing the Investment Annual Summary data
Now that you have all of the data ready for the report you're creating, you can start making plots that will be included in the report to help your audience visualize the data when they're reading the report. You'll start by creating a line plot of the investment_annual_summary data.

Exercise instructions
- Load the
ggplot2package in the first code chunk, after thedplyrpackage on line10. - In the
investment-annual-summarycode chunk, create a line plot using theinvestment_annual_summarydata. - Plot the fiscal year (
fiscal_year) on the x-axis, and investment amounts (dollars_in_millions) on the y-axis. - Color the plot by
region, so that the plot in the final report displays each region as a different color in the line plot.
