This calculation does not need to be calculated manually b

": +, "target": +, "value": 3}, {"source": +, "target": +, "value": 3}, {"source": +, "target": $, "Value": 5}]}The data consists of two parts, point (nodes) and edge (links), and the value of source and target represents the element that corresponds to the value subscript of the nodes array.Note that regardless of how many attributes the nodes element has, both source and target temporarily point to the person's name, such as Source 1 Target0, which represents Napoleon and Myriel connectionsBy
