JSON Crack – Visualize JSON data into graphs
If you indent your code manually then you can achieve something that I feel looks quite similar. So the example they give would be written as:    {"squadName":  "Super hero squad",
     "homeTown":   "Metro City",
     "formed":     2016,
     "secretBase": "Super tower",
     "active":     true,
     "members":    [{"name":           "Molecule Man",
                     "age":            29,
                     "secretIdentity": "Dan Jukes",
                     "powers":         ["Radiation resistance",
                                        "Turning tiny",
                                        "Radiation blast"]},
                    {"name":           "Madame Uppercut",
                     "age":            39,
                     "secretIdentity": "Jane Wilson",
                     "powers":         ["Million tonne punch",
                                        "Damage resistance",
                                        "Superhuman reflexes"]},
                    {"name":           "Eternal Flame",
                     "age":            1000000,
                     "secretIdentity": "Unknown",
                     "powers":         ["Immortality",
                                        "Heat Immunity",
                                        "Inferno",
                                        "Teleportation",
                                        "Interdimensional travel"]}]}

I've been doing with  Clojure/EDN data and I feel it makes it much easier to visually parse.PS: Does anyone knows if there was an emacs mode that'd do this for me automagically?
