Walkthrough understandability could be improved

Thanks so much for making this walk through (https://r-graph-gallery.com/183-choropleth-map-with-leaflet.html). However, because of the data used and the pipeline process for producing the choropleth, it's not very clear how to produce a similar aesthetic on different data. If you could more clearly separate the tile content data from the choropleth mapping, that would make it much easier to understand how to create our own choropleths. Thanks
