I'm building out a home automation suite. I'll be blogging about it on my new Forem Hometechnica in detail if you want to follow me there.
But a question for DEV in general: What are some libraries for visualization... It's a broad question, but right now I'm willing to be very exploratory with my approach to displaying lights being on or off, or showing the state of things in a floor plan, or anything like that.
Literally anything that could be used to create interactive visuals would be great to hear about!
