I am attempting to create a point that scales in relative size to a particular integer (frequency) and is gradiented to a particular integer value, and then overlay that point onto each specific polygon of a shapefile (USA)
The point should look something like this where darker colored points denote higher numbers and larger circles denote higher frequencies.
I have frequencies all values (included frequencies) joined to the USA shapefile, but am unable to create the points.
Are they buffers?
I'm new at this (QGIS).
