Finding correlations in complex datasets   5 comments

It is now almost three years since I moved to Boston to start working at Fathom Information Design and the Sabeti Lab at Harvard. As I noted back then, one of the goals of this work was to create new tools for exploring complex datasets -mainly of epidemiological and health data- which could potentially contain up to thousands of different variables. After a process that went from researching visual metaphors suitable to explore these kind of datasets interactively, learning statistical techniques that can be used to quantify general correlations (not necessarily linear or between numerical quantities), and going over several iterations of internal prototypes, we finally released the 1.0 version of a tool called “Mirador” (spanish word for lookout), which attempts to bridge the space between raw data and statistical modeling. Please jump to the Mirador’s homepage to access the software and its user manual, and continue reading below for some more details about the development and design process.

At Fathom (and first tablet app)   Leave a comment

Hello! A few days ago I started working at Fathom, the information visualization studio run by Ben Fry. While here I will work on various data visualization projects, specially those requiring real-time, interactive graphics with OpenGL, as well as continue with my involvement with the development of the Processing language and environment. This job also encompasses an exciting collaboration with the lab of Pardis Sabeti at Harvard university, focused in the creation of new tools for visualizing epidemiological data and helping understand the factors that determine the origin and spread of various diseases. During my first week at Fathom I got started by working on an Android port of the “Stats of the Union” visualization, originally available for iPad tablets.

Using Processing to create Cytoscape plugins   4 comments

Cytoscape is a cross-platform, open source application for visualization and analysis of networks. It is widely used in the field of Systems Biology to visualize different types of biological networks (like protein-protein interactions). It also has a plugin mechanism for extending its core functionality. Cytoscape is written in Java, so this open the possibility of using Processing to create Cytoscape plugins. I just put together a small template for creating Processing plugins for Cytoscape using Eclipse, keep reading for more details.
