Your SQLite database should have a schema that looks like this:

CREATE TABLE nodes(
  id INTEGER PRIMARY KEY NOT NULL,
  x FLOAT NOT NULL DEFAULT 0,
  y FLOAT NOT NULL DEFAULT 0
);

CREATE TABLE edges(
  source INTEGER NOT NULL REFERENCES nodes(id),
  target INTEGER NOT NULL REFERENCES nodes(id)
);
