- 添加 SVG 最大高度限制（桌面端 600px） - 使用 Flexbox 实现图表在容器中居中显示 - 添加响应式适配（平板 500px，手机 400px） - 设置容器最小高度 100px，避免空白过小 - 使用 width: auto !important 保持图表原始宽高比 - 创建尺寸优化测试文件和文档 解决问题： - 低内容图表（2-3 节点）不再显示过大 - 图表尺寸更加合理，视觉协调 - 复杂图表高度限制，出现滚动条 - 移动端体验优化

<h2>🎯 优化说明</h2>
|
||
<h3>主要改进：</h3>
|
||
<ol>
|
||
<li><strong>最大高度限制</strong>：SVG 最大高度设置为 600px（桌面端）</li>
|
||
<li><strong>居中显示</strong>：使用 flexbox 让图表在容器中居中</li>
|
||
<li><strong>宽度自适应</strong>：使用 <code>width: auto !important</code> 让图表保持原始宽高比</li>
|
||
<li><strong>响应式适配</strong>：
|
||
<ul>
|
||
<li>平板（<768px）：最大高度 500px</li>
|
||
<li>手机（<480px）：最大高度 400px</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>最小高度</strong>：容器最小高度 100px，避免空白过小</li>
|
||
</ol>
