Timeline, according to Journalist's Resource,
helps you build visually attractive chronologies. You simply fill out a Google spreadsheet template and drop in dates, links and associated media. The application’s Embed Generator then creates code that you cut and paste into your website, allowing you to host the timeline. (See Six Web-based tools and applications that can help you communicate visually.)
Two solid examples of the power of this tool are Revolutionary User Interfaces (see above) and Timeline: Egypt in Turmoil. What are some of the ways you could see this tool being used in advocacy or fundraising? Leave your thoughts in the comments section.
