What happens when you combine data and Web 2.0?
Mountains of data are piling up in libraries and corporate intranets, but how do we say it visually and make data more useful? Fichter looks at new online tools that enable sharing, analysis, and data visualization to show trends, associations and new insights on your library website that quickly engage, inform, and empower your customers to create their own visualizations. Tools such as Many Eyes go beyond the data visualization and tap into the social dimension encouraging sharing, collaboration, and reuse. Fichter talks about what happens when data goes “social.” From visual dictionaries, textual analysis of works of fiction, to star size and nutritional components of Big Macs, hop on board for this fast-paced look at an amazing set of tools that are at your fingertips.
