I want to achieve the radition effect with Carto like this url https://carto.com/blog/telefonica/

Can I develop it with Torque.js?

  • You'll have to a be a lot more precise about what "radiation" is for anyone to help you. – lynxlynxlynx May 24 '18 at 10:44

You need to follow quite a few steps, but you have a fully documented example here

Basically, you need to compute the full circle lines, split them into points, assign them a correct identifier or timestamp and then use Torque to render that in the browser.

The SQL looks hard but it's just quite a few steps with a few postgis/postgres tricks.
