我对思维导图有些疑问。我正在遵循以下模板：
我似乎无法互换这两个代码。我面临的两个主要问题是：
1- 像第二个链接那样为子节点创建子节点，特别是为“a3”创建 2 个子节点，为“b3”创建 3 个子节点。
2- 像第二个链接那样为边缘制作渐变颜色。
我也觉得“c”应该是“a”的子项，而不是不同的范围，因为它们是相连的，这使我想到问题 1。一个加分项是重新排列整个网络，使其看起来更美观（边缘交叉更少）和更小（特别是高度更低），边缘更短。
请查看下面的 MWE，任何帮助都将不胜感激。谢谢！

它产生以下内容：
答案1
在需要的地方嵌套

我在这里提出一些修改：
使用
small mindmap而不是那些缩放因子并放大字体（这是我的经验之谈：使用原始设置读取字体是一种折磨）。改变一些子项的位置；这大大改善了这一点，因为您可以避免许多交叉连接器；特别是
grow=<angle>子项的选项在这里非常有用（请参阅a6下面c2的代码）。
修改后的代码：

为选定的连接栏添加纯色（即非阴影）似乎并不像我想象的那么直接；在下面的例子中，我定义了一个connection bar color允许分配纯色的键（尽管可以使用，circle connection bar switch color=from (<color>) to (<color>)但这可能会在计算上很繁重，因为在后台它是一种阴影）：

答案2
另一个建议。此解决方案添加了c一个子节点，并a为子节点添加了子节点。此外，还为父节点定义了 a，这样当子节点有自己的节点时就可以看到渐变效果（参见子节点 a3、b3 和 c）。您可能希望删除命令以探索其他可能性。注意：控制第一个子节点从 40 度 CW 开始，同时控制子节点之间的分离。a3b3concept color=blue, text=blackconcept colorball color=<some color>clockwise from=40sibling angle=30
