graphviz的輸出SVG

Question

我使用的graphviz得到SVG回

dot -Tsvg graph.dot -o file 

1. 如何設定的Graphviz輸出SVG爲「矩形」節點而不是「多邊形」
2. 和翻譯設置爲（0 ，0）不（4 256）

非常感謝

<g id="graph1" class="graph" transform="scale(1 1) rotate(0) translate(4 256)"> 
<polygon fill="white" stroke="white" points="-4,5 -4,-256 265,-256 265,5 -4,5"/> 

digraph G { 
     a1 [id=a1 shape=rectangle]; 
     a2 [id=a2 shape=rectangle]; 
     a3 [id=a3 shape=rectangle]; 
     a4 [id=a4 shape=rectangle]; 
     a5 [id=a5 shape=rectangle]; 
     a1 -> a5; 
     a2 -> a1; 
     a2 -> a5; 
     a3 -> a2; 
     a4 -> a2; 
     a4 -> a4; 
}

Answer 1

1. 有一個在graphviz的不支持的爲2.2.1版本

的graphviz-2.2.1 - dotneato /普通/ svggen.c

文件的graphviz-2.2.1.tar.gz> graphviz的-2.2.1>dotneato›common›svggen.c 或http://graphviz.sourcearchive.com/documentation/2.2.1/svggen_8c-source.html

嘗試搜索 「<多邊形」 與 '<矩形'。零秒。
