story_maplibre

Create a scrollytelling story map with MapLibre

Provides an interface to the 'Mapbox GL JS' (<https://docs.mapbox.com/mapbox-gl-js/guides>)
and the 'MapLibre GL JS' (<https://maplibre.org/maplibre-gl-js/docs/>) interactive mapping libraries to help users
create custom interactive maps in R. Users can create interactive globe visualizations; layer 'sf' objects to create
filled maps, circle maps, 'heatmaps', and three-dimensional graphics; and customize map styles and views. The package
also includes utilities to use 'Mapbox' and 'MapLibre' maps in 'Shiny' web applications.
