Plotting minimum wages over time

Let's look at the trends for the minimum wage in the United States. You have access to the dataset wages_stats, containing the minimum, maximum, and median minimum wage for each year:

53x4 DataFrame
Row | year   median   max      min
    | Int64  Float64  Float64  Float64
____|_________________________________
   1| 1968   8.55     15.61    8.55
...

All wages are adjusted for inflation, so you are looking at the equivalent amount in the year 2020. Comparing the three lines corresponding to median, maximum, and minimum over time, can you spot any interesting trends?

The wages_stats and the DataFrames and Plots packages have been loaded for you with the using keyword.
