Open-source core technology behind VizHub and VizHub Pro — a platform for building interactive data visualizations with D3 and React.

This GitHub organization contains the foundational libraries and tools that power VizHub’s editor, runtime, and collaboration features.

VizHub is a platform for learning, teaching, and building production-quality data visualizations for the Web.

It is developed by VizHub, Inc., founded by Curran Kelleher, and has been used since 2018 by students, educators, and professional teams to create interactive visualizations with modern web technologies.

VizHub exists in multiple forms:

• VizHub (vizhub.com)
  The public, education-focused platform with a free tier and a paid Premium plan, widely used in courses, workshops, and self-guided learning.

• VizHub Pro (pro.vizhub.com)
  A professional, team-oriented platform for building serious data visualizations with collaboration, AI assistance, and secure infrastructure.
  (Currently in active development — private beta available.)

• VizHub Studio
  The expert services arm of VizHub, delivering fixed-scope data visualization engagements.
  The VizHub Studio Sprint is a one-week, $5,000 engagement delivered inside VizHub Pro.

This organization hosts the open-source components that make VizHub possible:

• vzcode
  An in-browser code editor for data visualization, built on
  CodeMirror and ShareDB for real-time collaboration.

• vizhub-runtime
  A secure sandbox for executing and rendering visualizations, built on
  Rollup and Sucrase.

• editcodewithai
  A one-shot, LLM-driven source code editing tool used to power AI-assisted workflows.

These projects are designed to be useful independently, and are also composed together in VizHub’s hosted products.

VizHub is built in the open because data visualization is both a craft and a teaching discipline.

Open source enables:

• Learning by reading real, production code
• Reuse across frameworks and environments
• Long-term sustainability beyond any single product
• Community contributions that improve the ecosystem for everyone

Build the world’s best open environment for learning, teaching, and creating data visualization.
