[Qgis-user] How do I achieve this symbol effect?

[Charles Dixon-Paver]

I can think of 2 easy ways to do this (if I understand the requirements
correctly), using either rule based rendering, or the geometry generator on
with stacked symbols. I imagine rule based rendering might be more
performant in some situations depending on the queries used, but for our
use case I feel either would be appropriate.

I set up a demo project with example styles in sample.gpkg:

I hope this answers your question
