Draw a Use Case Diagram for a voting machine, on which voters can see a list of candidates and select one to vote for. The machine should check that each voter is eligible to vote. The electoral registrar will also want to print a summary of the total votes for each candidate, and (separately) a list of the voters who have voted, and a list of those who havent. In case of a dispute, the machine should also list a complete record of who voted for whom, but only a judge can use this function.
