At the Open Visualization Collaborator Summit, we’ll bring together an international audience of developers to discuss how they are using open-source tools to build applications for geospatial analysis, biological research, AI training, and beyond. Our goal is to foster collaboration, encourage contributions, and shape the future of open-source visualization across disciplines.

Who?

We are contributors who maintain open-source libraries at the heart of the Open Visualization community — including deck.gl, GeoDa, and Cosmos; developers who build amazing applications with them; and folks who are passionate about data visualization in general. Come along to dive into topics like browser-based rendering, GPU-accelerated data processing, and scientific visualization. Share your work, meet others facing similar challenges, and help define the future of the open visualization ecosystem.
