I would like to make the icon displayed on the map 'pulsating'.
For example, using the color of the point. For instance, white-green-orange-red-black icon. The pulsation speed ranges from once every 5 seconds to black pulsing once per second. I would like the pulsation to be like a ring of the same color, which extends from the edge of the icon to a point, then disappears and starts over.
The animation should be handled by the browser through node.js.
Does anyone have experience with this?"
