on_section

For a given <code>story_section()</code>, you may want to trigger an event when the section becomes visible.
This function wraps <code><a href="/link/shiny%3A%3AobserveEvent()?package=mapgl&version=0.2.1" data-mini-rdoc="mapgl::shiny::observeEvent()">shiny::observeEvent()</a></code> to allow you to modify the state of your map or
invoke other Shiny actions on user scroll.

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.
