I was intrigued by why David did not use geom_label() for his Data Viz Class Exercise. It took me a while to figure out that geom_text() requires less code. After much trial and error, I was able to replicate the figure using geom_label() after learning to request show.legend = FALSE, and declaring linewidth = 0. See below:

median_income_yamhill |> ggplot( aes(x = amount, y = geography, label = amount_formatted, fill = geography) ) + geom_col(show.legend = FALSE) + geom_label( aes(x = 10000, label = geography), color = "white", linewidth = 0, show.legend = FALSE ) + geom_label( aes(label = amount_formatted), hjust = 1.1, color = 'white', linewidth = 0, show.legend = FALSE ) + scale_fill_manual(values = c("Yamhill" = "darkgreen", "Oregon" = 'gray')) + labs(x = NULL, y = NULL) + theme_void()
