### ggrepel
<https://github.com/slowkow/ggrepel>

Repel overlapping text labels away from each other.

```{r, message=FALSE,warning=FALSE}
# Example from https://github.com/slowkow/ggrepel
library(ggplot2)
library(ggrepel)

## We can repel the text labels away from each other by loading ggrepel and using geom_text_repel instead:
set.seed(42)
dat <- mtcars[1:8,]
ggplot(dat) +
  geom_point(aes(wt, mpg), color = 'red') +
  geom_text_repel(aes(wt, mpg, label = rownames(dat))) +
  theme_classic(base_size = 16)

#geom_label_repel is based on geom_label.
set.seed(42)
ggplot(dat) +
  geom_point(aes(wt, mpg)) +
  geom_label_repel(
    aes(wt, mpg, fill = factor(cyl), label = rownames(dat)),
    fontface = 'bold', color = 'white',
    box.padding = unit(0.25, "lines")
  ) +
  theme_classic(base_size = 16)
```
