2013-4 Generating Structured and Labelled SVG

This article discusses the importance of providing structure and labelling within SVG code, particularly when the SVG code is generated indirectly by a high-level system and when the SVG code describes a complex image such as a statistical plot. We argue that this is a desirable goal, but that many high-level systems that generate SVG do not provide sufficient structure and labelling. An example of a system, based on R, that does provide structure and labelling, is described to demonstrate that the goal is acheivable and we highlight the crucial features of this system that we see as important factors in achieving this goal.

2013-3 Generating unique names in gridSVG

The gridSVG package exports grid images to the SVG image format for viewing on the web. This article describes the problems associated with retaining grid object names in SVG element id attributes. In addition, new features in gridSVG that allow manipulation and retrieval of generated id attributes are discussed. These new features allow for easier and more predictable development of interactivity in plots generated by gridSVG.
