Many Eyes (2007)
With F. Viégas, J. Kriss, F. van Ham, and M. McKeon
Many Eyes is a free site where anyone can upload, visualize, and discuss data.
It is an experiment created by the Visual Communication Lab.

sense.us (2006)
With Jeff Heer and Fernanda Viégas
A web project allowing social, visual exploration of U.S. Census
data. The site supports view sharing,
discussion, sophisticated graphical annotation and social navigation. Sense.us was an
IBM internal site (Jeff's project as an intern in my lab), but you can
watch a video demo.

at Berkeley.

Baby Names and Social Data Analysis (2005)
With Laura Wattenberg
An online visualization of baby name trends over the past century. This
applet was originally created to celebrate the publication of my wife's
book on baby names. Its surprising popularity, and the social kind of data
analysis it spurred on blogs and online forums, helped change the
direction of my visualization research.

History Flow & Wikipedia studies (2003-6)
With Fernanda Viégas
In 2003, Fernanda and I decided to investigate the dynamics behind editing
in Wikipedia. History flow is the method we invented to make sense of the
data we collected. We went on to study other aspects of Wikipedia,
including the emergence of a new form of bureaucracy.

Chromogram (2006)
With Fernanda Viégas and Kate Hollenbach
How do you visualize a list of tens of thousands of words? A "chromogram"
translates those words into colors, using a straightforward alphabet-based
code, and plots them on a timeline. Although the method seems almost too
simple to work, it was effective in uncovering some surprising patterns in
Wikipedia editing histories.

ForumReader (2003)
With Kushal Dave, David Millen, and Michael Muller
A visual conversation browser. ForumReader presents a graphical
overview of a large conversation to let users scan and access hundreds
of messages rapidly.

Word Tree (2007)
With Fernanda Viégas
A word tree is a visual search tool for unstructured text,
such as a book, article, speech or poem. A graphic version of
the traditional concordance or keyword-in-context seach, it lets you pick a
word or phrase and shows you all the different contexts in which it appears.
The contexts are arranged in a tree-like branching structure to reveal
recurrent themes and phrases.
See the
description on Many Eyes.

PivotGraph (2005)
A new technique for visualizing and analyzing complex graph structures, such as social networks.
The method is designed for graphs that are “multivariate,” i.e., where each node is associated with several attributes.
Unlike visualizations which
emphasize global graph topology, PivotGraph uses a simple grid-based approach to focus on the relationship between
node attributes & connections.

Jigsaw Maps (2005)
The quest for a "perfect" treemap algorithm led me to create this variant,
a jigsaw map. I proved that this layout, based on the geometry of
space-filling curves, is optimal in a certain mathematical sense. In 2006
this layout was independently invented and popularized in the wonderful
comic XKCD to map the internet.

QuerySketch (2001)
A technique to query a time-series database, such as historical stock
market performance data, by sketching a target graph. This simple,
intuitive interface allows instant composition of complex queries (e.g.
performance opposite to a current portfolio for diversification; response
to a historical event). Online demo

Map of the Market (1998)
A visualization that allows users to see performance of hundreds of stocks
at once, with a rich context of industry and value information. A new
algorithm lets an existing visualization technique, the treemap, scale
more effectively. The resulting transparent view of the market has been
widely adopted by financial institutions and investors.
