Amazing!！
The directional diagram is visually clear.
However, those constantly shifting electric field lines are actually quite difficult to understand; I find this way of expressing it a bit strange, haha.
I understand that this was meant to convey a sense of polarization, but it still feels strange.
Since it's an "electric field," we need to express it using the concept of a "field."
Furthermore, the polarization is not exactly the same in all directions. For example, with a helical antenna, when viewed along its axis, the radiation patterns from the front (head) and rear (rear) are exactly opposite in direction; and when viewed radially (side), it becomes purely linear polarized. This is called "handedness," which is typically represented by different colors on a sphere. The "axial ratio" is similar.
If you want to express it dynamically, you should include the Poynting vector.
For example (Po Yin Ting vector, from Wikipedia):
The original image moves, but after pasting it, it no longer moves.https://upload.wikimedia.org/wikipedia/commons/thumb/3/3a/Shotcut-dipole-axis-labels-larger.gif/500px-Shotcut-dipole-axis-labels-larger.gif）
For example, the image below shows the far-field radiation pattern and polarization hand diagram for a 4-element circular quad antenna.
If we were to approach this in a very rigorous way, it would become quite complex and essentially turn into a post-processing tool for an electromagnetic field simulation software. This might require making some compromises.
