i tried a lollipop chart. I could not have it arranged by descending order below is my code


grand_pastics_tbl %>% filter(! %>% arrange(desc(grand_total)) %>% head(20) %>% mutate(country=factor(country)) %>% ggplot( aes(x=country, y=grand_total) ) + geom_segment( aes(x=country ,xend=country, y=0, yend=grand_total), color="grey") + geom_point(size=3, color="#69b3a2") + coord_flip() + theme( panel.grid.minor.y = element_blank(), panel.grid.major.y = element_blank(), legend.position="none") + #Add all my labels labs(title = "Top 10 Countries contributing to total Plastic Pollutions Worldwide", subtitle = "Out of all cleanup events in 2019 and 2020, these 10 countries had the most plastic items that were made by the company.", caption = "Data from | Viz by Erick Yegon|Glamour of Graphics Courseby RfortheRest of Us", y = "Grand total count (all types of plastic)", x = "Country") +

#All theme elements theme(legend.position ="none", panel.background = element_blank(), #remove gray background axis.text.y = element_text(face = "bold", size = 10), #no y-axis tick labels axis.ticks.y = element_blank(), #no y-axis tick marks axis.ticks.x = element_blank()) #no x-axis tick marks

Wondering if you can suggest a way to map data to a symbol. E.g. to plot a bird abundance value not as a bar or point but as a bird symbol, e.g. a lollipop with a bird at the end.
