This is a code chunk for R Markdown / Quarto:

```{r plot, message = FALSE, warning = FALSE, error = FALSE, echo = FALSE}
ggplot(mpg, aes(displ, hwy, colour = class)) + 
  geom_point()
```

What is the name given to this chunk?

Giving chunks good names are useful for finding code, accurately caching the output, and automatically naming figure files. Chunk names must be unique and not contain spaces.

Speaking of caching, what option would you use to cache this output?

```{r plot-line, 
 = TRUE}
ggplot(economics, aes(date, unemploy)) +
  geom_line()
```
