Observable

Observable is a data-exploration, analysis, and visualization platform that helps data analysts and their cross-functional stakeholders make sense of data. Its products include Observable Canvases (a collaborative, canvas-based data-exploration tool) and Observable Notebooks (reactive JavaScript notebooks for building interactive data visualizations with code). Observable also creates and maintains widely used open-source visualization tooling — D3.js, Observable Plot, Observable Framework, Observable Inputs, and the reactive Observable runtime — published as first-party npm packages. Backed by Menlo Ventures.

Observable is profiled on the APIs.io network. Tagged areas include Company, Data Visualization, Data Analysis, Business Intelligence, and Notebooks.
