#This is some data for a line chart

filter(Month == 5) %>%
select(Temp, Ozone, Wind, Day) %>%
pivot_longer(cols = 1:3)
#take this chart, and change the color of the lines so that
#Ozone is blue, Temp is orange, and Wind is green
ggplot(air) +

#take this plot and adjust the colors so that
#the bubbles are on a sequential scale from white to green

#generate some dummy data
