Analyze Revenue Trends - Bar Chart

One of the simplest but often neglected approaches to check the data is through visual inspection. In this exercise, you will create a bar chart of the revenue projections. Currently, the data is stored into two vectors, hist_rev (historical data) and rev_proj (projected data). We do this so that we can format the bar chart to make clear the distinction between actual revenues versus forecasted revenues.
