I use jq and jless and find that to be more practical than tools like these (not just because of being available in terminal).
When I have large blob of json, I am usually interested in first getting a high level idea of how it is structured (first few levels) then I either need to drill down or filter to find what I need. The combination of jless for interactive exploration and jq to make it easily scriptable/repeatable is quite nice.
I find it natural to reduce the json I start with to a subtree I can make sense of, and thus don't find myself lacking a tool which can provide a visual representation of the complete dataset.
