Ellipse Node

Overview

An ellipse is a geometric shape with asymmetrical major and minor axes.

Applicable scenarios:

Used to represent dynamic nodes, asymmetric relationships, or special shapes.
Suitable for representing flowcharts, network diagrams, or topology diagrams.
Commonly used in flowcharts, network diagrams, topology diagrams, etc.

设置 node.type 为 ellipse 以使用椭圆形节点。

Style Configuration

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

Example
