I have a layer with thousands of points.
I have been asked to represent this layer in way that can be easily seen the level of concentration of points in the layer. So when there is much point concentration, the zone should be darker (or redder i don't mind) and if there are few points the zone should be lighter (or greener).
I don't know exactly how to achieve this but i tried creating a buffer polygon for every point. The problem is that the color in this new layer is not added while elements overlay...
How could i edit the layer's style to achieve so in QGIS?
Another aproach that could be uselful is to obtain a raster image with red zones and green zones depending on the concentraion of points. I prefer to obtain a vector layer but if i can generate both layers better than best.
