Observable Framework
Observable Framework is an open-source static-site generator for data apps, dashboards, reports, and more. You write simple Markdown pages with interactive charts and inputs in reactive JavaScript. Framework includes a preview server for local development, and a command-line interface for automating builds & deploys.
The site you are currently viewing is a Framework project. We use Framework to organize and publish the course material, exercises, and assignments. The primer below was written by Will Wang and Jeffrey Heer.
