I made a tool for capturing data in JSON [0]. It's not in real-time but when I want to use my logs to troubleshoot something I have a local React project with https://github.com/plouc/nivo to make my own visualizations.

But for something you can host yourself I've used https://github.com/onejgordon/flow-dashboard in the past
