VizHub version 2 is the product currently deployed at https://vizhub.com. Source code for this is located in the vizhub-v2 directory. This codebase will remain deployed for some time with maintenance fixes from time to time, but active development energy is going towards VizHub 3.
VizHub has enough features to be useful for people who teach data visualization with D3 and React. It has been used in Data Visualization Course 2018, Datavis 2020, and [Get it Right in Black and White](

A re-write of VizHub is in progress, located in the vizhub-v3 directory. This is where active development is taking place.
Goals:
- Self-hosting - It should be possible to self-host your own instance using 100% open source code.
- Extensibility - It should be possible to extend the core with plugins that add features.
- Mobile UX - It should be possible to develop interactive visual software on a smartphone.
- Internationalization - The interface should be in your local language, for the global VizHub audience.
- Accessibility - The UI should be accessible, fully navigable by keyboard and screen reader.
This repository houses an archive of prototypes as a reference to draw from for VizHub 3 development.
- prototypes/open-core-first-attempt - An attempt at a modular architecture. Notable features here include: Server rendering, Proper ShareDB hydration, and Markdown rendering in a Web worker
- prototypes/vizhub-v3-false-start - An earlier false start at a VizHub rewrite. Notable features here include: Working PWA setup, new viz preview design, new home page design.
- prototypes/vizhub-v2-false-start - An ancient effort. Notable features here include: CodeMirror 6 integration, dynamic code editor theming, fonts with ligatures.
