DESCRIPTION

In the book Beautiful Evidence, Edward Tufte describes sparklines as small, high-resolution, graphics embedded in a context of words, numbers, images.

This module provides a relatively easy interface for creating different kinds of sparklines. This class is not intended to be used to build large, complex graphs (there are other modules much more suited to that job). The focus here is on the kinds of data well-suited to the sparklines concept.

See SVG::Sparkline::Manual for the full usage documentation for the module.

INTERFACE

SVG::Sparkline->new( $type, $args_hr )

Create a new SVG::Sparkline object of the specified type, using the parameters in the $args_hr hash reference.

See SVG::Sparkline::Manual for the details.

get_height

Returns in height in pixels of the completed sparkline.

get_width

Returns in width in pixels of the completed sparkline.

to_string

Convert the SVG::Sparkline object to an XML string. This is the method that is used by the stringification overload.

DIAGNOSTICS

Diagnostic message for the various types are documented in the appropriate SVG::Sparkline::* module.

CONFIGURATION AND ENVIRONMENT

DEPENDENCIES
