everyone I'm new here, but not so new in physics. I have read many articles about EM wave to find what I'm searching for and nothing still. I have seen many pictures, animations and videos about EM wave, and about oscillating charge, but still nothing. What I am really curious about is why there is no animation or picture about electric and magnetic field together ftom the point of an oscillating charge, but there is only electric field shown. e.g.
It tells me that is something like this
and that these circles are magnetic field of moving charge, but they are actually showing crest or trough of an electric field, i.e. electric wave, right?
So another question follows, is electromagnetic wave really how it looks like in many pictures and animations? e.g.
Forgive me for my bad english, it is not my native language and I'm not using it very often.

For electrodynamics simulations I have found the following applets particularly useful.

Below is a screenshot of the TE electrodynamics simulation showing a still frame of the electromagnetic fields of an oscillating electric dipole. The arrows represent the strength and direction of the electric field. The magnetic field is represented by red and green shading for magnetic field into and out of the screen respectively.
You can control the frequency of the waves and what fields are displayed - enjoy; I have.
