Draw a graph in a circle with a vertex in the middle

1. The program will present directed and undirected graphs with specified parameters:
• number of vertices n;
• location of peaks;
2. Create a program for creating an image of directed and undirected graphs in a graphics window.
The above-mentioned parameters of the graph are set on the basis of the four-digit but mayor variant n1n2n3n4(n1=3,n2=4,n3=2,n4=7 The number of vertices n is equal to 10+n3
Place the graphs in a circle with the vertex in the center of the circle it should look something like this, but now I only get this way.
Here’s the code, help me if you can!

Помогите, пожалуйста, как-то исправить это, ибо я не силен в windows forms
