/**
 * @brief Generic graph view for r2 graphs.
 * Not all r2 graph commands output the same kind of json. Only those that have
 * following format
 * @code{.json}
 * { "nodes": [
 *      {
 *          "id": 0,
 *          "tittle": "node_0_tittle",
 *          "body": "".
 *          "out_nodes": [1, 2, 3]
 *      },
 *      ...
 * ]}
 * @endcode
 * Id don't have to be sequential. Simple text label is displayed containing
 * concatenation of label and body. No r2 builtin graph uses both. Duplicate
 * edges and edges with target id not present in the list of nodes are removed.
