构建一个以 `dino_vectors` 为顶点的 `Polygon` 对象，画出将每个点相连的恐龙

def solve():
    import matplotlib.pyplot as plt
    
    dino_vectors = [(6,4), (3,1), (1,2), (-1,5), (-2,5), (-3,4), (-4,4),

    x = [v[0] for v in dino_vectors] + [dino_vectors[0][0]]
    y = [v[1] for v in dino_vectors] + [dino_vectors[0][1]]
    
    plt.figure(figsize=(8, 6))
    plt.plot(x, y, 'b-', linewidth=2)
