## `sf` for interactive maps

We provide the option of how to use `sf` class object to create interactive maps. It requres the `leaflet` package.

    pd_county <- csmaps::nor_county_map_b2024_default_sf
    leaflet::leaflet(
      pd_county,
      options = leaflet::leafletOptions(preferCanvas = F)
    ) %>%
      leaflet::addProviderTiles(leaflet::providers$Esri.WorldGrayCanvas) %>%
      leaflet::addPolygons(
        weight = 0.3,
        opacity = 1,
        color = "black",
        fillColor = "white",
        fillOpacity = 0.9
      )
