```

This short video shows the core `dragmapr` loop on an actual map: open the
draggable helper, move regions and labels, and use the exported state to create
a reproducible static map.

```{r demo-video, echo = FALSE, results = "asis"}
in_pkgdown <- identical(Sys.getenv("IN_PKGDOWN"), "true") ||
  isTRUE(getOption("pkgdown.in_pkgdown"))

if (in_pkgdown) {
  cat('
<div class="dragmapr-demo-video">
  <video controls preload="metadata" poster="../dragmap-demo-poster.png" src="../dragmap-demo.mp4">
    <p>
      Your browser does not support embedded video.
      <a href="../dragmap-demo.mp4">Download the dragmapr demo video.</a>
    </p>
  </video>
</div>
')
} else {
  cat("[Watch the dragmap demo video on the pkgdown site](https://prigasg.github.io/dragmapr/articles/dragmap-demo.html).")
}
```

The same workflow can be run locally with the bundled examples:

```{r, eval = FALSE}
library(dragmapr)

hhs <- example_hhs_layout()

drag_map_prototype(
  hhs$states,
  region_col = "hhs_region",
  labels = hhs$labels,
  region_offsets = hhs$region_offsets,
  label_offsets = hhs$label_offsets,
  region_palette = hhs$region_colors,
  open = TRUE
)

render_dragged_map(
  hhs$states,
  region_offsets = hhs$region_offsets,
  region_col = "hhs_region",
  labels = hhs$labels,
  label_offsets = hhs$label_offsets,
  region_palette = hhs$region_colors,
  region_labels = hhs$region_names,
  title = "US Map by HHS Regions"
)
```
