On May 21, the Obama administration launched Data.gov, a web site that provides access to raw data from federal government agencies. Access to this raw data is useful, but to unleash the power of the data, you need tools for visualizing it. Today, we’re going to show you how to use Google Fusion Tables to visualize and analyze data from Data.gov. Fusion Tables, which we launched in Google Labs in June, is a system for managing data in the cloud, combining powerful features of desktop database systems with easy-to-use collaboration tools. You can read more about it on the Google Research Blog.
Before we start with Fusion Tables, let’s find a data set from Data.gov to use. Go to the Data.gov Raw Data Catalog and enter some keywords to find data you’re interested in. I’m interested in recent earthquakes. Make sure you select the “CSV/Text” file type – we need data in that format to be able to load it into Fusion Tables.
