As a retired weather guy with over 25 years working with and training weathermen, this is one of the best tools I've seen. Applause!
Understanding fluid flow and visualizing it is not easy, but it crucial to meteorology because that dynamic drives and reveals the mechanisms that create the weather systems we track, such as fronts, storms, and so on. Given the tools seen are usually something like this (from ADDS)
or this (from CoolWx)
, the WindMap does a much more intuitive job of showing the strength and patterns in merging flow.
So, well done! The only improvement I can think of for better use operationally would be an hourly looper of, say, the past six hours with a 3-4 second pause for each hour. This would let you track specific features as the day goes on.
