graphviz output svg

Question

I use graphviz to get the svg back

dot -Tsvg graph.dot -o file

1. How to set the Graphviz output svg to "rect" node not "polygon"
2. and the translate is set to (0,0) not (4 256)

thanks a lot

<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. There is no support of in graphviz as of version 2.2.1

graphviz-2.2.1 - dotneato/common/svggen.c

file graphviz-2.2.1.tar.gz›graphviz-2.2.1›dotneato›common›svggen.c or http://graphviz.sourcearchive.com/documentation/2.2.1/svggen_8c-source.html

try to search "<polygon" and '<rect'. Zero for second.
