h2o-wave 1.4.0

Python driver for H2O Wave Realtime Apps

H2O Wave is a lightweight software stack for programming interactive web applications entirely in Python (no HTML/Javascript/CSS required).

It is designed to make it fast, fun and easy to build low-latency, realtime, collaborative, web-based applications. It ships batteries-included with a suite of form and data visualization components for rapidly prototyping analytical and decision-support applications.

Wave’s components work in conjunction with the Wave relay server that facilitates realtime state synchronization between Python and web browsers.
