C++ and Web Application - pedestrian simulation

I was wondering if it is possible to write my pedestrian behavior simulation in C++ as backend and visualize this simulation in frontend with HTML, CSS and JS. I would like to create a web application where a user could set some parameters, then send these parameters to backend C++ server and server creates an instance of multithreaded simulation (each pedestrian would be a single thread) and that simulation will send as JSON data about pedestrians to frontend, where all will be visualize. I consider using WebSockets to provide data from backend to frontend and for simulation using cellular automata's approach.

Could you recommend me some frameworks or technics I should use to achieve my goal? Or maybe you see a better solution for this issue. I will really appreciate any help.
