Manuel Tan from uncontrol.com has published a small appilcation to visualize discussions. Attributes like rating, amount of words and count of replies indicate how vibrant discussions about a specific article are.
Commentry is an interactive 3d visualization of comments on a popular digg story. Digg’s rating system combined with word counts allows us to see the status as well as health of a story. Heated debates can easily be found as well as popular reactions(good or bad) made by a given user.
The visualization is a three dimensional rotating Pie Chart. Each slice represents a comment about the story. It’s word count is represented by the width, the amount of replies by the length and the rating from “positive” to “negatve” is indicated by the color.
Recently there have been repeatedly great discussions about Pie Charts (1, 2, 3) (Okay, there have always been discussions about their usefulness). What are your thoughts about the usage of a three dimensional Pie Chart for the Commentry visualizations?
