Visualization

# Dumbbell Chart

  geom_dumbbell(size = 1, size_x = 3,  size_xend = 3, colour = "#AFAFAF",  
                colour_x = colors[1],  colour_xend = colors[2]) +
  labs(title = "Dummbbell Chart", x = "Life Expectancy (years)",
       y = "country") +

  theme(text = element_text(family = "Arial"),
        plot.title = element_text(size = 12,hjust = 0.5),
        axis.title = element_text(size = 12),
        axis.text = element_text(size = 10),
        axis.text.x = element_text(angle = 0, hjust = 0.5,vjust = 1),
