It supposed to accept user input. User have to fill the table(adjacency matrix) like so:
The max amount of nodes would be 10 or so.
Then you should be able to press something like "plot graph" button and it draws the appropriate graph for you:
The problem is how can i draw a graph?

How do you do this? a Windows Desktop Application? As far as Windows Desktop Application concerned, There is a graphics device interface, such as GDI+, allows application programmers to display information on a screen or printer without having to be concerned about the details of a particular display device.
I think that you should decide how to place the nodes in your window. For example, you can distribute them on an imaginary circle using simple trigonometrical operations. Then use the drawing functions of Graphics class, such as DrawLine, FillEllipse, DrawEllipse. To draw the arrows, see https://learn.microsoft.com/en-us/windows/win32/gdiplus/-gdiplus-drawing-a-line-with-line-caps-use. You will probably need some additional mathematical research, which is probably an interesting purpose of this exercise.
In C++/CLI (CLR), you can use MSAGL
(add references to Microsoft.Msagl.GraphViewerGdi.dll, AutomaticGraphLayout.Drawing.dll)

Hello,
have a look at this code:
cppgraph
index.html
Edit: and have a look at this: free-c-library-for-drawing-flow-diagrams-or-directed-graph
