Pastel is a format independent graphics layer that
just happens to generate SVG.

There are two ways that can be done as I can think of.

#1. Replace all the GD call with Pastel call so that
Bio::Graphics generates SVG.

#2. Let Pastel handle the call to GD or generate SVG

Here is the psedocode

User file:

use Bio::Graphics::Chromatogram;
$ch =
Bio::Graphics::Chromatogram->new(width...height...etc);

$ch->set_trace(@a);

$ch->draw_svg();
or
$ch->draw_png();

In Bio::Graphics::Chromatogram:
The first case:

use Pastel;

draw_svg {
  Pastel::Graphics->new();
