A pulsating circular element in the UI is an indicator of something real-time. Adding such an element next to charts with constantly updating data is a fine visual cue.

• Box Shadow: Cast shadow around the element

  /* offset-x | offset-y | blur-radius | spread-radius | color 
  */
  box-shadow: 2px 2px 2px 1px rgba(0, 0, 0, 0.2);

• Scale3d: Resize the element in 3D space
