I have a shapefile of the locations of wind turbines within the central flyway. I was attempting to show the size by the total number of turbines however I am having a problem with many large scale farms being close to each other and it's taking away from the message. I was wondering if there was a way to merge points within a certain distance so that instead of have 9 separate points I could have one large point? I have inserted the image below.
Have you considered using a heat map style? It'll remove all the points and show areas of highly clustered turbines. It can also be based on the attribute of the number of turbines at each site rather than their proximity to each other (as long as you have that number in the attribute table).
In the style properties of the point layer change the style from 'Single symbol'/'Categorized' (whatever you're using in your image) to 'Heat Map'.
Set the 'Weight points by' to the attribute that has the turbine numbers for each site.
See what it looks like then play around with the radius property to get a good spread of the heatmap. Also changing the 'Layer blending mode' to Overlay or multiply will let you see the basemap beneath more clearly than just changing the layers transparency.
