Web 2.0 is opening the doors to tools and toolkits for do-it-yourself (DIY) programming that requires no knowledge about programming. Find out what mashups are and how libraries are making use of them to create rich, new information services and content. Look at some of the intriguing and robust new data visualization tools, such as IBM’s alphworks, swivel, gapminder (bought by Google), etc. that can put the power of spreadsheets online for everyone in your organization to present their information as tag clouds, bar and pie charts, bubble maps, and more.
