DESCRIPTION
My talk from the Data Visualization Summit in Boston on September 12, 2013. This talk will explore Filtergraph, a web application being developed by Vanderbilt’s Initiative in Data-Intensive Astrophysics to conduct rapid and intuitive visualization of large multi-dimensional datasets. Filtergraph has been designed with an understanding of the cognitive workflow in big-data exploration, enabling users to quickly, easily, and intuitively delve into massive datasets and quickly find emergent patterns in the data. While Filtergraph was designed for astronomy research projects at Vanderbilt, including searches for extrasolar planets from databases involving millions of stars, Filtergraph has broad potential for generating flexible, colorful and interactive data-visualization portals using a wide variety of data sources. Currently, Filtergraph has more than 100 users in 20 countries. Filtergraph is freely available at http://filtergraph.vanderbilt.edu/.

• Large amounts of data– Tens of columns–Millions of rows
• Need for exploratory data analysis– Bad data, missing data, categories,
biases, relationships, patterns
