Observable Notebooks

In plain words

Observable Notebooks is a platform for creating interactive documents that combine code, visualizations, and narrative text. Launched in 2018, it enables developers and data professionals to build and share dynamic computational notebooks in the browser. The tool is designed for those who want to explore data, prototype ideas, or communicate findings through live, runnable code alongside explanatory content, making it useful for education, research, and data analysis workflows.
