Use (IDW/bilinear) interpolation with kepler.gl

First of all, it's pretty quick to load geojson data with kepler.gl,
and it supports [Time Playback function](https://docs.kepler.gl/docs/user-guides/h-playback)
that's the reason why I choose kepler.gl instead of leaflet to render huge geojson data.

I've read some examples about interpolation such as [turf.js](https://turfjs.org/)
[PM2.5 IDW](https://pm25.lass-net.org/GIS/IDW/) and [earth](https://earth.nullschool.net/)
but I don't know how to use it with kepler.gl

This is the effect that i wonder

Probably interpolation is a process before i upload data to kepler.gl,
Please tell me if this is an unrelated issue,thanks!
