Math.NET庫提供了一些基本的圖形繪制方法，可以用來繪制線條、曲線、圓形、矩形等基本圖形。以下是一些常用的圖形繪制方法：
using MathNet.Spatial.Euclidean;
Vector2D start = new Vector2D(0, 0);
Vector2D end = new Vector2D(100, 100);
Line2D line = new Line2D(start, end);
using MathNet.Spatial.Euclidean;
Vector2D controlPoint1 = new Vector2D(50, 50);
Vector2D controlPoint2 = new Vector2D(80, 80);
BezierCurve2D curve = new BezierCurve2D(start, controlPoint1, controlPoint2, end);
using MathNet.Spatial.Euclidean;
Vector2D center = new Vector2D(50, 50);
double radius = 25;
Circle2D circle = new Circle2D(center, radius);
using MathNet.Spatial.Euclidean;
Vector2D topLeft = new Vector2D(0, 0);
Vector2D bottomRight = new Vector2D(100, 100);
Rectangle2D rectangle = new Rectangle2D(topLeft, bottomRight);
這些方法可以用來創建相應的圖形對象，然后可以根據需要進行進一步的操作或顯示。
