This GIF es from dribbble.

I've tried to write a demo with pure CSS, here's part of my codes:

@keyframes circles{
  0%{
    transform: scale(0) rotate(150deg);
  }
  100%{
    transform: scale(1) rotate(0deg);
  }
}

They won't rotate as a whole.

The mixing animation at the center of the gif is not required, I just want to realize the rotating effect.

Hope someone can help me.

This is a pound or nested movement. The break down is:

• The dots themselves are just sliding along a straight line inwards and scaling a little bit as they travel
• Each dot's start time is offset slightly from the last so they appear to travel in sequence, which gives the illusion of a swirl.
• Finally, the dots would all be grouped under a parent element who's only job is to rotate.

Following this approach, you can easily apply simple translation and rotation animations to each element and still get this swirling effect.

This is a bit late, but here is my jsfiddle following @Soviut's answer

https://jsfiddle/hfpymtba/

The 'spin' animation is applied to the container

@keyframes spin{
  0%{
    transform: rotate(0deg);
  }
  100%{
    transform: rotate(360deg);
  }
}

The 'graviton' animation is applied to the circle classes

@keyframes graviton{
  100%{
    top:50%;
    left:50%;
  }
}

There is a bit of wobble as the circles aren't perfectly around the centre of the container.
