Add data, optionally symbolized by a column

With column supplied this is add_choropleth(); without it, add_geojson(). Provided for parity with the Python API.

Usage

add_data(map, data, column = NULL, name = "Data", ...)

Arguments

map

A GeoLibre widget.

data

GeoJSON as a parsed list (a FeatureCollection, Feature, or bare geometry), a JSON string, a file path, an HTTP(S) URL, or an sf object. A URL or file is read and inlined into the project, up to a 50 MB limit; for larger datasets prefer add_vector(), which lets the browser stream the source.

column

Optional numeric property to drive graduated symbology.

name

Layer name.

...

Forwarded to add_choropleth() or add_geojson().

Value

The modified widget.

Examples

point <- list(type = "Point", coordinates = c(-77, 39))
map <- geolibre() |> add_data(point, name = "Point")
