## Using an SVG icon from the web


This example grabs an SVG from the internet and then uses it as a 
plotting glyph without further modification.


```{r fig.height=1, eval=FALSE}
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Read SVG from the web
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
car_url <- 'https://www.svgrepo.com/download/114837/car.svg'
car_svg <- paste(readLines(car_url), collapse = "\n")
```


```{r eval=TRUE, echo=FALSE}
# Local cache
car_svg <- paste(readLines("svg/car-svgrepo-com.svg"), collapse = "\n")
```



```{r fig.height=1}
grid::grid.draw( svg_to_rasterGrob(car_svg) )
```


```{r fig.width=6, fig.height=4}
ggplot(mtcars) + 
  geom_point_svg(
    aes(mpg, wt),
    svg = car_svg,
    size = 8
  ) + 
  theme_bw()
```
