While trying to find a useful way having earthquakes displayed, I noticed that it isn't that easy to manage.
I'd like to be able to recognize the "Magnitude", "Date", and "Depth" from the style of the point. Something like:
- size: based on magnitude
- depth: basic color (ex. <15 red, 15-30 yellow, >30 blue)
- date: intensity of color as shading from 100% color to white/...
Is there a way to do so without defining dozens of rules?
