I knew that Geometry Generators are powerful, but this powerful?!! Thanks for the awesome demonstration, Klas! I'm gonna be busy playing more with the generator.

If the raster doesn't fill the map extent you could use this as a fallback value:

buffer(
scale_exp(
COALESCE(
0 -- or another fallback value
), -150, 3500, 0, @distance, 0.5 ))

Hi Klas I have a problem when add the the geocoding for point size the expression builder says: "Unnvalided expression (Cannot convert to geometry). And it isn't make sense cause I write literally the same code of you. (I use QGIS 3.34 long term release)

Could help me?

Hej Klas, bra video som vanligt! Jag har en fråga till dig. När jag arbetar med QGIS hemma så fungerar allt smärtfritt. Men så fort jag inte arbetar hemma så är QGIS otroligt långsamt. Nästan som om den laddar från en databas. Det är samma långsamma upplevelse även om jag är hemifrån och arbetar med en fil/mapp som är sparad på skrivbordet på datorn. Jag är ganska ovis och undrar om du vet vad detta kan vara för fel?
