I tried the periodic table in their examples using sonnet 4.6 on the $20/mo plan. After a few minutes Claude told me it reached the max message length and bailed. I pressed continue and eventually it generated the table, but it wasn't inline, it was a jsx artifact, and I've now hit my daily usage limit.
I’m intermittently getting artifacts vs the new visuals api, depending on which version of the Claude app I use. iOS/iPadOS apps are not yet supporting the visualization API, and I don’t see an app-store update yet.
