Assuming you are using toJSON method of Graphic to generate the json object (in your example data). Then the correct way of creating a Graphic from the json object is to use the "reverse" method fromJSON. Something like this should work,

const [Graphic] = await loadModules(["esri/Graphic"]);
// here use fromJSON method to create the graphic
let g =  Graphic.fromJSON(data); // data which is json i gave.
