Dash Labs tech preview

This repository contains a work-in-progress technical preview of potential future Dash features.

🚧 Dash Labs features are not guaranteed to land in the official dash package. These features are also not officially supported by Plotly's Support Team or by Dash Enterprise. We recommend waiting for these features to land in dash before using them in a Production Environment. 🚧
