Open Visualization
Collaborator Summit 2026

ETH Hönggerberg
Building HIL Room E7
Stefano-Franscini-Platz 5,
8049 Zürich, Switzerland

On September 9-10, 2026, come together with the vis.gl/deck.gl community to discuss the present & future of the leading open source library for visualization on the web.

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, kepler.gl, GeoDa, and cosmos.gl; 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.
