[OME2026] Poster: TissUUmaps 4: Facilitating Community Contributions to Spatial Biology Visualization

Abstract: TissUUmaps is an open-source, interactive web application for visualizing large multi-modal spatial omics datasets, including point clouds, vector geometries, and tiled image pyramids. While known for its GPU-enabled rendering of millions of points and static exports for publication, the TissUUmaps project is currently undergoing a major architectural modernization. This poster highlights the core features of TissUUmaps 4, its alignment with modern community standards such as OME-Zarr, and its new architecture designed to facilitate community contributions and long-term maintenance.
