TagMaps is a toolkit to visualize text (well, tags) geographically on a map. TagMaps is available as a Flash component for your own website. The tags input to the visualization can be drawn from your own application - or you use the data API of one of our sample applications, World Explorer, where we used TagMaps to visualize Flickr tags on a map. TagMaps is a research prototype from Yahoo! Research Berkeley. We'd love to hear your questions or comments; please come visit our blog and drop us a line.

In this tutorial, you learn to build a link graph with XML, PHP, and JavaScript code. Link graphs are paragraphs of keywords in which the size of each word depends on some data value -- in this case, the frequency of the term. The more often the term occurs, the larger the font size of the word. This tutorial shows how to build an RSS parser that in turn builds a keyword list along with the word frequencies. It also demonstrates how to use XSLT to create an HTML page that shows the link graph and relates its term to its original article.
