Hello, i have a dataet with a set of long and lat, and there are roughly 300k datapoints, my goal is to create a sensible depiction of point distribution across the united states. It looks horrible, is there a way to maybe get density or a sum of points?. I tried the following
ggplot() +
geom_polygon(data=map_data("usa"),aes(x=long,y=lat,group=group),fill=NA,color="black") +
geom_point(data=h1b,aes(x=h1b$lon,y=h1b$lat),color="yellow",size=1)
its from this dataset:
It would help to have an example of the sort of visualization you are aiming for (even for a different dataset), but it sounds like you are maybe looking to make a choropleth map? If so, take a look at the choroplethr family of packages (which build on top of ggplot2).
Thank you so much already, I will definitely look into it and hopefully have no more question ( but i doubt it 
)
When 
you have more questions, I encourage you to ask them! (but do remember to start a new topic if it’s a new question) I learn a lot from what people ask, even if I don’t know the answer.
A tip: you’ll earn the heartfelt appreciation of your helpers (plus avoid friendly nudges 
) if you also read the FAQs on formatting your code and making a reproducible example and follow their advice as best you can.
Good luck!
