Some api naming issues that tend to make working with charting more difficult:
RadChart is in the Telerik.Windows.Charting.dll and is referred to as "Chart" in the documentation and RadChart in code.
However, RadChartView is in the Telerik.Windows.Controls.Chart.dll (where you would think to look for RadChart), is referred to in the documentation as "ChartView" and the even less obvious "RadCartesianChart" in code.
I'm sure as new assemblies and controls get created a need for backward compatibility must be maintained, so the Charting.dll reference is likely a product of that since it appears like new controls get added to the Controls namespace. But something should be considered for Chartview, either correcting the code name (which hurts upgrade-ability) or correcting the documentation (which is always a pain).
Also, on a related note, the link in the Chart documentation
that says "We encourage you to review our new control RadChartView
for super-fast visualization of your data." links back to the Chart documentation instead of the ChartView documentation.
