=== SVG and vector graphics ===

Perl graphics programming is not limited to raster images. Perl can also generate vector graphics, especially through the `SVG` module. MetaCPAN describes `SVG` as a 100% Perl module that generates a nested data structure containing the DOM representation of an SVG image. It can generate SVG objects, embed other SVG instances, access the DOM, create JavaScript, and generate SMIL animation content.<ref>MetaCPAN, “SVG,” https://metacpan.org/pod/SVG, accessed July 3, 2026.</ref>

SVG is important because it allows Perl to generate scalable diagrams, charts, maps, icons, and illustrations as XML-based vector graphics. Unlike PNG or JPEG output, SVG can scale cleanly and can be manipulated by browsers, editors, and scripts.

Perl-generated SVG is useful for:

* diagrams;
* flow charts;
* network maps;
* genome browser tracks;
* data visualization;
* icons and logos;
* scientific illustrations;
* interactive web graphics;
* generated reports;
* print-friendly vector output.

SVG fits Perl well because SVG is text. Perl is excellent at generating structured text, XML-like output, and data-driven documents.
