// fixed it by changing your "return d" to "return indx" on line 87
// personally, i suggest looping through the dataset, and appending the property code = 1 to
// every element instead of what we've done below. when we use the second argument in d3,
// by convention, it's to dictate which key to bind the data to the document, and not to
// modify the dataset. by modifying the data *before* we bind it, it makes things clear
// for subsequent readers
