public ActionResult Timeline()
{
var articleQuery = from a in artDb.dbArticle
select new { a.Date, a.StockPriceClose };
List<DataPoint> dataPoints = new List<DataPoint>();
foreach (var item in articleQuery)
{
double stockPriceClose = double.Parse(item.StockPriceClose.ToString());
DateTime date = Convert.ToDateTime(item.Date);
**
var dataPoint = new DataPoint(date, stockPriceClose);
dataPoints.add(dataPoint )
**
}
ViewBag.DataPoints = JsonConvert.SerializeObject(dataPoints);
return View();

Your code is using the viewbag object as json object, but it is actually a string,
JsonConvert.SerializeObject return type is a string you can check the documentation and see Return Value Type: A JSON string representation of the object.
ViewBag.DataPoints = JsonConvert.SerializeObject(dataPoints);
this will be string, you need to parse that string to JSON object,
you can use JSON.parse() function to do this.
dataPoints: JSON.parse('@Html.Raw(ViewBag.DataPoints)')
