I'd like to create some flow maps like the ones shown in Underdark's post: https://anitagraser.com/2016/12/18/details-of-good-flow-maps/

I have a set of location points, say 50, and I'd like to create one "all points to one" map for each point, thus 50 maps in this example. And another set of "one point to all" map for each point, so 50 maps more.

Instead of creating all the extra line layers, I'd like to accomplish this using a combination of Atlas and Geometry generator symbols in QGIS.

However, I'm not finding many examples to see how or if I can do it.

So, is there a site where I can find an exhaustive set of examples of QGIS geometry generator?

EDIT: This is a clip of the filtered output showing just the top 10 lines from each point. I created all the lines from a csv with the point coordinates using a WKT. Arrows and point symbols are created with the geometry generator. The rest is controlled by Atlas.
