 Using [mapview](https://r-spatial.github.io/mapview/):
 
 1. Show number of moth species per UTM 1x1km grid cell on a map. The color of the cells should represent the number of moth species. Use the provided code to read and manipulate the source datasets. Display the legend. Set the contour of the polygons in red. What happens when clicking on an area? Beautiful, isn't?
-
 2. Let's fine tune the previous  map. Use "OpenStreetMap" map tiles only, set
 the opacity of the areas to 0.9 and the contour lines to 0.2. Set `"number of
 moth species"` as legend title and layer name. Hint:

 3. Create a separate map with the municipalities of Pajottenland. Use black as line color. Set
  layer name as `"municipality"`. Again, allow Open Street Map tiles only.
  No legend. Set line width of the polygons to 1 and set opacity of the polygons to 0.
-
 4. Combine the two maps. Make sure the hover text still shows the number of
  moth species.

 5. You have already installed leafem, so you should see by default the mouse coordinates (lat, lon) and zoom level on top left. If not, check how to add them in the [extra leaflet functionalities](https://r-spatial.github.io/mapview/articles/mapview_06-add.html) vignette. Add also the INBO coding club logo to the map with a link to the INBO coding club homepage: https://inbo.github.io/coding-club/. Link to the image is provided in the R code.
