Live demos

Every demo below is the real Spatial Data Studio viewer, running in your browser against a saved checkpoint. There is no server: the page fetches byte ranges out of a .sdata.zarr.zip as you pan, zoom and change what you are looking at.

That is the same thing that happens when you open a checkpoint without the app running — these pages just point the viewer at files hosted alongside the documentation.

What you can do here

Colour the cells by a category or a gene, switch the image channels on and off and adjust their contrast, change the point size and shape, and open the Embeddings view. The analysis history in the sidebar shows the steps that produced the data.

What you can't

A checkpoint is read-only and there is no backend to compute against, so running new analyses, editing labels and saving are all unavailable. Anything you change here stays on your screen and is gone on reload.

The demos

Fluorescence sectionOpen in a new tab

1,800 synthetic cells over a three-channel image. Try colouring by cell_type, then by one of the marker genes.

Tissue microarray coresOpen in a new tab

A 3×4 grid of cores laid out from real Xenium human lung cells.

You can also open the whole collection in the viewer's own gallery, which is what a deployed folder of checkpoints looks like.
