ExcentricLabelRFC

TableOfContents([2])

Proposal

This is an RFC to create a core Cytoscape plugin that will support "Excentric Labeling".

First off, what exactly is "Excentric Labeling"?

• "Excentric labeling is a dynamic technique of neighborhood labeling for data visualization. When the cursor stays more than one second over an area where objects are available, all labels in the neighborhood of the cursor are shown without overlap, and aligned to facilitate rapid reading. A circle centered on the position of the cursor defines the neighborhood or focus region. A line connects each label to the corresponding object."[1]

Here is an example, taken from [1]:

Background

This RFC is the result of Allan Kuchinsky's initial exploration / evaluation of the InfoVis_Toolkit. As part of his evaluation, Allan built several prototypes, including one which demonstrates the excentric label features provided by InfoVis. There is a movie of the prototype available at: http://cytoscape.org/cgi-bin/moin.cgi/InfoVis_Toolkit?action=AttachFile&do=get&target=test_excentric.avi
