I'm plotting ACS data (counts of low-income children) for each county across the entire U.S. I don't have any markers, just a county shapefile and a value for each county in a popup.
Unsurprisingly this is too large for browsers to handle. I've seen some similar questions here that deal with clustering, but since I have nothing to cluster I'm starting a new question.
I've tried breaking it up into 4 regional maps, but even those are too much.
Is there some way to lower the footprint, but still have all the county specific data?
I'm using R to generate the map, so R-specific responses are helpful but not necessary.
