Your dates are not input correctly. The correct way to input dates in the Viz API's JSON format is a string in the format "Date(year, month, day[, hour[, minute[, second[, microsecond]]]])", where month is zero-indexed (so January is 0 not 1). Assuming your dates are in the format "year-month-day", you would input "2013-06-01" as "Date(2013, 5, 1)".
