, then you can calculate the corresponding angle of each node, into the trigonometric expression, you can get the curve above the point coordinates, the node directly assigned to this position can be. In the example above, you can see that the connection between nodes is near the center of the ellipse, not at the center of the ellipse, and how does this work? This side is related to an expansion of the node type, this side will be named Busedgetype, just like bus route, change more paragraphs, w
