Features

The Feature set will be focused on five themes:

Relational Analysis (RaVis) Methods of analysing relationships, structures, and links among objects.

• Graph theory algorithms such as Radial, Hierarchical, and Force-Directed;
• Self-contained – all mathematical processing is performed within the library;
• Control – degrees of separation, data filtering, item rendering, drag and drop, look and feel, visibility, events, dataproviders, etc.

GeoSpatial Analysis (GeoVis) The analysis of locational and geographic data.

• Rendering of vector-based maps with control to style geographic objects (e.g. regions, countries, states), add symbol overlays, events, projections, coordinate addressing, etc…
• Custom maps via svg path data, shapefile readers, and KML/GML configurations;

Quantitative Analysis (QaVis) Conventional and novel methods of numerical and statistical analysis.

• Treemap
• MicroCharts, Sparklines
• Venn diagrams, bullseye, pyramids, polar/spider charts, etc…
• Conventional chart and graph methods

Temporal Analysis (TaVis) The analysis of data that varies over time.

• Components to support chronology and date/time analysis

General Utility (GuVis) Concepts and techniques of information visualization and visual design.

• Coraldata – a robust API of data structures
• Distortion (Fisheye / BiFocal)

SpringGraph is a 2D data visualization API based on the flex 2. I have used flex 3 sdk to demo the example of spring graph.

first of all, a package should be downloaded for using SpringGraph at developer blog. Extracting the package, copy ./SpringGraph/bin/SpringGraph.swc to the directory named simple.

The package provides five examples for testing SpringGraph. going into simple SpringGraphDemo. using command to compile the mxml file, like:
mxmlc -library-path+=../SpringGraph.swc SpringGraphDemo.mxml

than using a flash player open SpringGraphDemo.swf. the interface should like this example.
