The concept is based on a folksonomy as data structure. Tags describe a set of information visualizations from various points of view. These tags are organized in a classification scheme and are grouped into three categories (Data, Visualization, Interaction) and different bundles (e.g. the tag “text” is organized in the bundle “data type” and belongs to the category “Data”). The data set contains 700 visualization projects that are stored with title, description, preview picture, and a link to the project website.

The resulting DelViz (Deep exploration and lookup of Visualizations) concept supports different search tasks: finding suitable information visualizations for a given context, and analysis of the underlying structured data set to discover relationships between the visualization. To support these search tasks, the application offers two flexible areas: the representation of the categories, bundles and tags on the left-hand side, and the information visualizations presented as thumbnails on the right-hand side. A splitter in the middle can be used to expand one of these two areas to change the level of detail on either side.


The prototype is developed in Microsoft Silverlight using Deep Zoom Composer (only available in Internet Explorer).
