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 Powerful easy-to-use tools for data integration, visualization, analysis and reporting. Using DIVA, we can carry out common and necessary tasks in a faster and more efficient manner. Bring together data from disparate locations and organize using new pivot, merge and summary features. Easy to learn and use, DIVA facilitates sharing of information, using powerful new reporting features.
