I have not see a way to customize the API somehow to be able to add a custom label or container that can hold a part of the date(e.g. Year) as the time-lapse is playing. The year will update from 2017 to 2018 as the visualization is playing.

Describe the solution you'd like A clear and concise description of what you want to happen.

Being able to extract the year into its own container on the final time-lapse visualization.

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.
