Google is your friend: Be nice and visit him often. He can answer questions a lot more quickly than posting them here...

A very quick search gave nearly half a million hits: simple pie chart c - Google Search[^]
Including this Codeproject article: Create Pie Chart Using Graphics in C# .NET[^]
The code is in C#, but it's pretty trivial, and if you really can't work it out there is an online translator here: Code Converter C# to VB and VB to C# – Telerik[^]

In future, please try to do at least basic research yourself, and not waste your time or ours.
