Observable is the destination for data visualization—is launching for developers, data scientists, journalists, educators, and more to explore, analyze and visualize data on the web, together.

Observable reimagines how we can make sense of data for this modern, connected world, making it more approachable, accessible, and social — maybe even fun. 

Observable was founded in 2017 by Mike Bostock and Melody Meckfessel. The company is headquartered in San Francisco, California.


Observable is democratizing data literacy and supporting those who want to understand and visualize data transparently in real time. The platform empowers creators to further their learning through data visualization and, ultimately, gain deeper insights.


Observable’s collaborative data canvases are built for and powered by a deeply engaged community of more than five million people engaged.


Observable and its community has created the largest library of data visualizations for exploring and gaining insights. Together, this community is learning from and inspiring each other to create the future of collaborative data work.
