I had a look in VS2013 with a .NET 4.5 WinForms project, and can see the
Chart control in the Toolbox under "
Data".
When I look in the .NET Framework Components I see two entries for Chart:
System.Web.UI.DataVisualization.Charting
System.Windows.Forms.DataVisualization.Charting
Here you can find some tips on how to fix this:

You could try downloading the Chart controls for .NET 3.5 (which is probably also on your system), from here:
Download Microsoft Chart Controls for Microsoft .NET Framework 3.5 from Official Microsoft Download Center[

Otherwise it might be needed to uninstall and install the .NET 4.5 framework again using the webinstaller,

Hope this helps !
