php - graphviz svg autoresize -

i've got graph made graphviz circo (or dot, guess in issue there's no difference) in svg format , i'd image resized automaticly. know can done if set

<svg width="100%" height="100%"...

but can't realize how make circo this.

the graph file circo generated in php this:

$graph = "digraph structs { node [shape=record, url=\"http://localhost/gr.php?object=\n\"]; overlap = prism; size=\"50,50\";` 

i've tried size=\"100%,100%\"; circo translates <svg width="3600pt" height="2946pt". so, how can make circo put 100% in there? thanks!

the thing worked me is

$svg = file('circo.svg'); $svg[6] = preg_replace("/\d+pt/","100%",$svg[6]); //the line number fixed foreach($svg $line) {     echo "$line"; } 

maybe =)
