In order to integrate Charting for WinForms into your Visual Studio project, select the Manage Nuget Packages command from Project menu:

Open the Browse tab, and enter MindFusion.Charting in the search field. Select the MindFusion.Diagramming package and click Install. If you plan to use other MindFusion components along with the chart (such as diagram, calendar, spreadsheet), select MindFusion.Pack.WinForms instead:

Once the package is installed, you should be able to add controls from the library to your UI (Dashboard, BarChart, LineChart, etc).
