Use time slider to represent temporal data using GeoJSON in a 3D scene

[caesarW]

Hi everyone, I'm currently using ArcGIS API Javascript 4.18 version. Suppose I have the location information with the related number of people (crowd) over time (e.g. 1 month, 10 mins interval). This data is stored in GeoJSON. I'm now facing difficulty in showing the crowd size at different times.

This project is in a 3D scene, the location data and building shape is stored in the GeoJSON.

I was wondering how to construct a GeoJSON that can store the crowd data in a given 10 mins interval across few months and represent the number of the crowd using a color ramp.
The below is my data, screenshot. Thank you very much.
