Looking For Contributor 3D representation of data for PoC

Hello, I need a simple, minimal 3D environment, using webgl, getting from an external source the initial data and updates (coordination, shape, etc) about objects present on the scene. This a proof of concept for a system that I want to create, but can't seem to fine enough time to learn Unity, being busy enough with the "external source" part. I'd prefer cooperation for fun and creating something potentially wonderful, without promising immediate funding or hiring someone to just do the job.
