 Note that the first option, called `"modes"` is not really an option, but rather a list of mode-specific options, where the first subitem of each item is the name of that mode. Here, the technical rather than the user interface mode names are used: `"Grid"` for the `"plot"` mode and `"Leaflet"` for the `"view"` mode. The other subitems are either totally new options, or standard options (also listed further below) but with different defaults.

 All options with the name prefix `value(s)` refer to default values for visual variables/values. E.g. `value.const` and subitem `fill.polygons` is the default polygon fill color.
 
-The options `scales.var` specifies which scale are used by default to map data variables to visual variables. This depends on the visual variable and the data type. E.g. for numeric data ("num") and the visual variable `size`, the `continuous` scale is used, so `tm_scale_continuous()`. For the visual variable `text` (of `tm_text()`) the scale `asis` is used, so `tm_scale_asis()`.

 There are two modes included in **tmap**: `"plot"` for static mapping and `"view"` for interactive mapping. See [introduction](https://r-tmap.github.io/tmap/articles/basics_modes). The `"view"` mode uses the JavaScript library Leaflet as backend.
 
-The extension package [**tmap.mapgl**](https://r-tmap.github.io/tmap.mapgl/) offers two new modes which are also interactive: `"mapbox"` and `"maplibre"` which use the JavaScript libraries Mapbox GL and Maplibre GL respectively. An API key is requires to use `"mapbox"` (free for personal use), but `"maplibre"` is (as the name suggestions) free for any use.

 Note that *tmap.mapgl* is a bridge between the R packages *mapgl* and *tmap*. It makes the functionality of *mapgl* (making the JavaScript libraries available to R) also available via the *tmap* user interface.
