.net - Is there any difference between system.web.datavisualization and system.web.UI.datavisualization -

I have found a good article on the ASP.NET website. Scott Mitchell, author, uses a section called Chart () , which he said was the system. Web. UI comes from DATV Visualization. But, when I try to reference system.web.UI.datavisualization names from my project, I do not see this by looking at the .NET tab. Instead, I'm getting system.web.datavisualization (without the UI between the system and DataVisualization).

I am surprised that we are talking about the same namespace. If this is not the case, then how can I get the system? Web. UI DATVLIGATION and how to install it?

Thank you for helping.

class System.Web.UI.DataVisualization.Charting is located in the namespace (There is UI ) in the System.Web.DataVisualization.dll assembly (no UI not)

.NET Displays a list of tabs related to the add context window (not namespace) of the tab, so that you can System.Web.DataVisualization ( System.Web.UI.DataVisualization .charting ).
