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

CREATE TABLE nodes(
  x FLOAT NOT NULL DEFAULT 0,
  y FLOAT NOT NULL DEFAULT 0
);

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

Your nodes must have a unique integer rowid, which is the default behavior for all tables in SQLite.
