I have a map that I've divided up into a grid. I want to be able to show whether a grid sector contains at least one point. Due to the volume of points, it's impossible to render each point on screen, perform some sort of clustering, or get a count of the number of points in each grid.
Currently, if a sector has at least one point, it's shaded green. However, this approach isn't aesthetically appealing (see attached image). Any ideas on a better way to do this?
