Javascript Orderbook using FTX Websockets

I am looking for someone to create a vanilla javascript implementation of an bid/ask orderbook using the FTX.com public websocket API (https://docs.ftx.com/?javascript#orderbooks). It should have the functionality to group by a specified price granularity and display up to N results. A visual implementation of how it should look is here: https://www.binance.com/en/futures/ETHUSDT (note this is a different exchange, but shows the proper look and functionality)
