Here is our sample data, created from the preceding image, using only states up to two degrees of separation away from Florida (FL):

CREATE (FL:State {code: "FL", name: "Florida", population: 21500000})
CREATE (AL:State {code: "AL", name: "Alabama", population: 4900000})
CREATE (GA:State {code: "GA", name: "Georgia", population: 10600000})
CREATE (MS:State {code: "MS", name: "Mississippi", population: 3000000})
CREATE (TN:State {code: "TN", name: "Tennessee", population: 6800000...
