Я разработал простое приложение с AngularJS, и я хочу добавить простую диаграмму на основе этого сайтаJs Charts

Это моеdata.json:

Но все равно не работает, он не может загрузить график

У меня как ошибка:

Ошибка типа: не удается прочитать свойство 'тип' из неопределенного

ОБНОВЛЕНИЕ 2 :

Я установил это в plunkr:plnkr.
