i've been using visidata for visualizing json and csv in table views, querying it, plotting it, etc. the node-link graph in here is something i wish visidata could do
Indeed, JSON For You is significantly behind visidata in handling table data compared to it. Their focuses are different, perhaps I can learn some highlights from its design. However, if you have needs for JSON processing, you might want to give JSON For You a try, haha.
visidata can handle arbitrary json data, even if it's not tabular in form, but there are a lot of things i don't know how to do with it. json4u's jq support looks like an improvement, for example. but many of those things are probably things vd can do but that i just haven't learned how to do yet
