Dynamic 2.5D Treemaps using Declarative 3D on the Web

Limberger, Daniel; Scheibel, Willy; Lemme, Stefan; Döllner, Jürgen

The 2.5D treemap represents a general purpose visualization technique to map multi-variate hierarchical data in a scalable, interactive, and consistent way used in a number of application fields. In this paper, we explore the capabilities of Declarative 3D for the web-based implementation of 2.5D treemap clients. Particularly, we investigate how X3DOM and XML3D can be used to implementclientswithequivalentfeaturesthatinteractivelydisplay2.5D treemaps with dynamic mapping of attributes. We also show a first step towards a glTF-based implementation. These approaches are benchmarkedfocusingontheirinteractioncapabilitieswithrespect to rendering and speed of dynamic data mapping. We discuss the results for our representative example of a complex 3D interactive visualization technique and summerize recommendations for improvements towards operational web clients.
