@yuntianyi-chen Thank you for your pr
I want to know what the problem is, increase the lethality, and add color?

The program would crash as the first image showed if the Apollo HD map contained crosswalks when you need to visualize them by calling the _draw_polygon() function.

TypeError: Polygon.init() takes 2 positional arguments but 3 were given

For this error, the constructor of matplotlib.patches.Polygon is Polygon(xy, closed=True, **kwargs), and closed is a keyword argument, not a positional one. But the original program passes it positionally, which causes the error.
