Hi,
<div><br>
</div>
<div>I have a similar research problem, and the dots seem to be a wonderful solution. </div>
<div><br>
</div>
<div>So, this email does not give any assistance re the original question, just an answer to the question below:<br>

Given that your polygons should generate a uniform density of dots within the area they bound, I don't see value in generating the dots for symbology.</div>

<div>The polygon area may vary, as it does in my research (distribution of burials in administrative areas). Therefore, a small area always looks underrepresented as compared to a larger area, and vice versa. I have large administrative areas with low densitiy,
but they look well populated even with a very light shade of grey. </div>
<div><br>
</div>
<div>So I would like to try to find a solution to Chris' problem since the representation with dots is closer to reality than colouring areas. I will report when I found a solution for my use case -- though this may be autumn...</div>
