sub readfile { my $filename = shift or return; ... }
If this code should only check that filename is defined (i.e. allow empty string), you can write (even for perl <5.10) it like this:
defined(my $filename = shift) or return;

Corion gives up
[Discipulus]: ah! so you mean if i need a static image i can use Twig, if on the fly better css selector and mody attrs (jquery?), rigth?
[LanX]: not sure what you guys are taking about, but a DOM manipulation in JS shouldn't be difficult
[Corion]: Discipulus: Yeah, that's what I would try (but so far, I can't even change the colors manually in the SVG, which is why I gave up ;) )
Discipulus bad sign..
[Discipulus]: italian doc says to modify somehow the initial SVG before using it with D3.js
[Discipulus]: LanX the fact is that my js ability is even poorer than my Perl one..
[LanX]: oh its negative? ;P
