DIVA

What Is Diva ?

• Diva is a software infrastructure for visualizing and

interacting with dynamic information spaces.

• Visualizations are built by hooking together software components which generate, supply, filter, and display information.

Diva Architecture

• The high-level Diva architecture is fundamentally based on the principle of separation of data and presentation.

• It consists of a collection of loosely-coupled components, that communicate and collaborate to produce meaningful visual presentations.

• Any given visualization system or tools is constructed from a set of these components -- some general-purpose and some purpose-written -- "glued" together in useful ways.

Example: The diva.graph demo

• The graph demo demonstrates basic graph editing and layout functionality.

• A graph is constructed programmatically, and can then be edited interactively by the user.

• The graph editor contains six operations: Select nodes, Reshape nodes, Move nodes, Add

nodes, Add edges, and Layout.

Demos contd….

• The diva.canvas demo: The canvas demo illustrates the main architectural features of the canvas.

• The diva.sketch demo: The sketch demo demonstrates free-hand drawing and basic editing commands using pen gestures.

• The diva.whiteboard demo: The whiteboard demo is a digital whiteboard which supports multiple pages, limited undo and redo support, multiple pen colors and widths, and other basic whiteboard capabilities.

• The diva.sketch.trainer application: Sketch trainer is a program that allows users to create customized gestures for their application (square, triangle,

circle, etc).

DIVA CAPABILITIES
