[Qgis-user] Velocity field rendering using PyQGIS

[afernandez]

Hello,
I need to programmatically render a velocity field. The closest example 
that I was able to find is 
https://opengislab.com/blog/2020/10/10/wind-vector-mapping-and-animation-in-qgis 
although I don't need the animation feature. The problem is that, even 
after reading the DeveloperCookbook, I'm still unsure how to code some of 
the visual steps, particularly when it comes to defining the symbology. I 
was wondering if anyone knows of any example involving velocity field 
rendering or has any tips on how to define & use the symbology.
Thanks.
