+# AssociativeLine plugin
+
+> v0.4.5+
+
+> The function of adjusting associated line control points is supported from v0.4.6+
+
+This plugin is used to support the addition of associative lines.
+
+The plugin is currently not fully functional, and does not support adding text to association lines.
+
+## Register
+
+```js
+import MindMap from 'simple-mind-map'
+import AssociativeLine from 'simple-mind-map/src/AssociativeLine.js'
+
+MindMap.usePlugin(AssociativeLine)
+```
+
+After registration and instantiation of `MindMap`, the instance can be obtained through `mindMap.associativeLine`.
+
+## Config
+
+Support for modifying the thickness and color of associated lines, divided into default and active states. The configuration is as follows:
+
+- `associativeLineWidth`: The thickness of the default state of the associated line. The default value is `2`
+
+- `associativeLineColor`: Color of the default state of associative lines. The default value is `rgb(51, 51, 51)`
+
+- `associativeLineActiveWidth`: The thickness of the active state of the associated line. The default value is `8`
+
+- `associativeLineActiveColor`: The color of the active state of the associated line. The default value is `rgba(2, 167, 240, 1)`
+
+The configuration is provided as a theme, so if you want to modify these four properties, you can modify them using the `mindMap.setThemeConfig(config)` method.
+
+## Props
+
+### mindMap.associativeLine.lineList
+
+Currently, all connection line data, array types, and each item of the array are also an array:
+
+```js
+[
+    path, // Connector node
+    clickPath, // Invisible click line node
+    node, // Start node
+    toNode // Target node
+]
+```
+
+### mindMap.associativeLine.activeLine
+
+The currently active connection line and array type are the same as the structure of each item in the `lineList` array.
+
+## Methods
+
+### renderAllLines()
+
+Re-render all associated lines.
+
+### removeAllLines()
+
+Remove all associated lines.
+
+### createLineFromActiveNode()
+
+Create an associated line from the current active node. If there are multiple active nodes, the default is the first node.
+
+After calling this method, an association line will be rendered from the first active node to the current mouse real-time position. When a target node is clicked, it represents completion of creation. An association line will be rendered between the first active node and the clicked node.
+
+### createLine(fromNode)
+
+Creates an associative line starting at the specified node.
+
+After calling this method, an association line will be rendered from the specified node to the current mouse real-time position. When a target node is clicked, it represents completion of creation, and an association line will be rendered between the specified node and the clicked node.
+
+### addLine(fromNode, toNode)
+
+Add an associative line directly.
+
+Calling this method will directly create an association line from the `fromNode` to the `toNode` node.
+
+### removeLine()
+
+Deletes the currently active associative line. Clicking on an associated line is considered active.
+
+### clearActiveLine()
+
+Clears the active state of the currently active association line.
