Example use case: @Isaac needed a dashboard for a dataset many dimensions. There was no easy way to set up a public visualization with our current tools, so he set up https://turnilo-public.wmcloud.org/ on a cloud instance he's managing.
I think it's a good solution for now, but I think the use case is generic and we should eliminate one-offs.
Dashiki was supposed to be our go-to tool for this kind of data, but we haven't followed through with it lately. This task should decide on a plan going forward, even if that's just accepting that we'll deal with one-off solutions until we can make a better plan.
