If you need an optimized chart, not a funny one that lags on weak devices like a 3D game, then the listed libraries are not very suitable for you.
The best option is pure SVG. SVG itself is already optimized for charts and responsive.
The best socket is UWS - ultra-light, fast, and secure. Almost all financial companies like Binance, Google... use it.
