## About
Ocks.org grew out of the original bl.ocks platform that Mike Bostock launched to let people share small, self-contained D3 demos. The site remains the go-to place for developers who want to study real code rather than abstract tutorials. Anyone can fork an existing block, tweak the data or styling, and publish their own version in seconds. The collection spans everything from simple bar charts to intricate network diagrams and geographic maps. Because every example runs in the browser with zero setup, it has become a favorite sandbox for students, journalists, and data teams at startups and Fortune 500 companies alike. The underlying engine is still pure D3, so users learn the library by reading and modifying actual production-grade code. Over the years the community has contributed thousands of blocks that cover animation techniques, responsive design patterns, and integration with modern frameworks. Ocks keeps the original lightweight feel while quietly adding small quality-of-life improvements such as better search and mobile-friendly previews. Revenue is not pursued; the project stays independent and funded by the maintainer’s own time plus occasional sponsorships from companies that rely on D3. The focus stays on open sharing rather than turning the site into a SaaS product. New visitors often arrive after seeing a striking chart on Twitter or in a news ar
