CubicHorizontal Bezier Curve

Overview

The horizontal cubic Bezier curve is a smooth curve with control points primarily distributed along the horizontal direction, suitable for connecting nodes horizontally.

Use cases:

Suitable for horizontally laid-out graphs, such as flowcharts and hierarchical diagrams.
Use when emphasizing horizontal connections is needed.

Note: When calculating control points, the distance on the x-axis is primarily considered, ignoring changes on the y-axis.

设置 edge.type 为 cubic-horizontal 以使用水平方向的三次贝塞尔曲线。

Style Configuration

If the element has specific attributes, we will list them below. For all general style attributes, see BaseEdge

Attribute	Description	Type	Default	Required
curvePosition	Relative position of the control point on the line connecting the two endpoints, ranging from `0-1`.	number \| number[]	[0.5,0.5]
curveOffset	Distance of the control point from the line connecting the two endpoints, understood as the degree of curve bending.	number \| number[]	[0,0]
