https://bookdown.org/profgarrett/course_r_eda/ggplot-2-making-the-plot-pretty.html

Then, walk through each section below. Each question matches to a section in the online guide.

Q1) Lines

Modify the ggplot below to add:

• A vertical line at 2012
  • hint: the axis is a date! Use ymd(‘2012-1-1’) as your value.
• A horizontal line at 100%
• A rectangle for the spike in 2022 (cover all dots above 125% in 2022)

Q2) Labels

Modify the ggplot below to add:

• geom_label_repel showing the title
• x and y label axis for ‘Price%’ and ‘Date’
• Use bw_theme

Q3) Scales

Modify the ggplot below to add:

• A continuous y scale, using label_percent rounded to 10
• A date x scale, using date breaks of 2 months
  • Note! Use date, not datetime, as the column doesn’t have a time component.
