Is this possible with Lottie?

So, I current have this very basic animation:


It’s a little plain, of course, but it’s based on direct manipulation of a SVG mask and it’s a pain to maintain.

I am wondering if a Lottie equivalent would be possible.


  1. It would take parameters: the year (e.g., 2021 in the above) and the percentage of completion (which currently decides how the mask is shifted in the above)
  2. It should work on the Web and in mobile Web browsers
  3. It should be scalable and responsive

Is that possible with Lottie?

@laurent Do you want to PM me to discuss this? I think I have an idea of what you’re looking for and can help out.
