Add System.Web.DataVisualization as an assembly reference. (It was located in the .net tab). Add the following statement:
using Charting = System.Web.UI.DataVisualization.Charting;
From there you will link to your charts this way
Charting.Chart myNewChart = new Charting.Chart();
This will help keep the namespace a little cleaner and probably avoid some clashes, as the vocabulary surrounding the world of graphics is not very unique.
