Scalability of the shiny application using vitessceR

[ashishjain1988]

Hi,

Thank you guys for creating a really nice package to visualize single cell data. Can you please tell us what is the scalability limit of the portal like in terms of number of cell, size of meta data, etc?

Regards,

We have this example of a Vitessce visualization that contains over 1 million cells http://vitessce.io/#?dataset=salcher-2022 The visualization scalability will ultimately depend on the characteristics of the user's computer as the rendering runs in the web browser on the client-side. In the context of R, when using local data, again the characteristics of the machine that is running the R process will affect the performance of any data transformation or conversion steps. Once data is in Zarr format, it can typically be served with little overhead as the Vitessce JavaScript code can make requests for subsets of the data as it is needed for visualization.
