 SimpleRandom

+
+## Example 
+
+First, load the packages we will use for this example
+
+```@example 1
+using BiodiversityObservationNetworks 
+using CairoMakie
+using GeoMakie
+import SpeciesDistributionToolkit as SDT
+```
+
+Using a Polygon as the domain
+
+```@example 1
+num_nodes = 50
+corsica = SDT.gadm("FRA", "Corse")
+bon = sample(SimpleRandom(num_nodes), corsica)
+```
+
+Now plot
+
+```@example 1
+f = Figure(size=(500, 500))
+bonplot(f[1,1], bon, corsica, axistype=GeoAxis)
+f
 ```
