Testing

• [x] Verify Lead values.

  // via http://stackoverflow.com/a/17040125
  var secondMax = function(arr) { 
    var max = d3.max(arr),
        maxi = arr.indexOf(max);
    arr[maxi] = -Infinity; // Faster than removing and inserting
    var secondMax = d3.max(arr); // Get new max 
    arr[maxi] = max;
    return secondMax;
  };
  
  votes["Lead"] === d3.max(votes)-secondMax(votes);

• [x] Verify Blues/Reds values.

  var coalitionLeft = ["A", "B", "F", "Ø"],
    coalitionRight = ["V", "O", "K", "I", "C"];
  
  coalitionSum = function(d, coalition) {
    var votes = parseFloat(0);
    for (var i = 0; i < coalition.length; i++) {
        votes += parseFloat(d[coalition[i]])
    }
    return votes;
  };
  
  d3.csv(dataset, function(error, data) {
    data.forEach(function(d) {
        coalitionSum(d, coalitionLeft) === votes["Red (A+B+F+Ø)"];
        coalitionSum(d, coalitionRight) === votes["Blue (V+O+I+C+K)"];
    });
  });

• [x] CSV Validity

  csvlint data.csv

  • Does not check for schema compliance nor 50.0 vs. "50,0", though.

Just need to present it as an HTML table now.

Also considering an option that hides inconsistencies < x.

NB: Any (minor) inconsistencies may be the result of relying on single-decimal values. This is why even the election result returns an error.
