FAQ pointing to visualization resources

We often get asked if we will implement visualization on the Portal. Right now, you can upload data you get from us (untested!!!) to kana (https://www.kanaverse.org/kana/) for visualization and analysis. We could add this information as an FAQ, after testing of course.

Review the existing FAQ structure and verify whether the provided ScPCA data can be uploaded to kana for visualization and analysis. Document the tested result and add the relevant resource information to the FAQ; done means the guidance is accurate and clearly identifies the kana link.
