Start the device:

```R
library(httpgd)
hgd()
```

Open the displayed URL in a browser, or call `hgd_browse()` to open one automatically.

Any plotting code will work:

```R
x <- seq(0, 3 * pi, by = 0.1)
plot(x, sin(x), type = "l")
```

```R
library(ggplot2)
ggplot(mpg, aes(displ, hwy, colour = class)) +
  geom_point()
```

Close the device when done:

```R
dev.off()
```
