2012-7 A Structured Approach for Generating SVG

The gridSVG package exports grid images to an SVG format for viewing on the web. This article describes a new development in the way that gridSVG produces the SVG output. The result is greater flexibility in how the SVG output is produced and increased opportunities to manipulate the SVG output, which creates new possibilities for generating more complex and sophisticated dynamic and interactive R graphics for the web.

2012-6 Working with the gridSVG Coordinate System

The gridSVG package exports grid images to an SVG format for viewing on the web. This article describes new features in gridSVG that allow grid coordinate system information to be exported along with the image. This allows the SVG image to be modified dynamically in a web browser, with full knowledge of coordinate system information, such as the scales on plot axes. As a consequence, it is now possible to create more complex and sophisticated dynamic and interactive R graphics for the web.

2012-5 Voronoi Treemaps in R

A Voronoi Treemap is a visualisation tool for displaying data with a hierarchical structure.  This article describes an open source implementation of Voronoi Treemaps in the R language and environment for statistical computing and graphics.  The article includes example usage for the main R functions and a detailed description of the underlying code.  The raw code itself is also available with this article.
