If you're reaching for a tool like this, it's because you don't have a well-defined schema and corresponding dedicated visualization; you're looking at some arbitrary internal or insufficiently-documented transfer-level data with nested structure, perhaps in the midst of a debug breakpoint, and need a quick and concise visualization without the ability (or time) to add substantial code into the running runtime. Especially if you're working on integration code with third parties, it's common to come across this situation daily.
