<p>尝试使用<a href="https://graphviz.gitlab.io/_pages/doc/info/attrs.html#d:ratio" rel="nofollow noreferrer">^{<cd1>}</a>属性：</p>
<blockquote>
<p>...</p>
<p>If ratio is numeric, it is taken as the desired aspect ratio. Then, if the actual aspect ratio is less than the desired ratio, the drawing height is scaled up to achieve the desired ratio; if the actual ratio is greater than that desired ratio, the drawing width is scaled up. </p>

<p>如果原始的图表是这样的：</p>
<p><a href="https://i.stack.imgur.com/tqENL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tqENL.png" alt="enter image description here"/></a></p>
<p>添加<code>graph [ratio="1.5"]</code>属性将使其看起来像这样：</p>
<p><a href="https://i.stack.imgur.com/LOr2v.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/LOr2v.png" alt="enter image description here"/></a></p>
<p>UPD：还要注意<code>ratio</code>属性是如何与<code>size</code>属性成对工作的，也许这种组合最适合您。详细的解释在比例文件的链接我已经张贴。你知道吗</p>
