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.
