The Challenger

If you want to push your R skills to the limit, let’s use another popular data visualization package called ggplot2.

For this challenge, we’ll try creating another map of average household income for Chicago communities, but instead of classifying our data into bins, or ranges, we will visualize it as a continous variable.

The code below is an example of what you’ll work with in the R markdown file.

ggplot(data = define_data, aes(fill = define_variable)) + geom_sf() + scale_fill_distiller(palette = "RdPu", direction = 1) + labs(title = "Give your map a nice header title here", caption = "Add a data source here", fill = "Add a legend title") + theme_void()
