Hi Andrea, That kind of error, "google is not defined", means that at the time you use the google symbol, the loader has not finished loading. I suspect the problem might be that ngOnInit is called before the component html has been defined and/or used, so the loader has not necessarily finished loading.
Since your app-component html really looks more like a full page, including html head and body, maybe you should separate out the chart drawing parts into a chart-component.
