DESCRIPTION
The Web, once solely a repository for texts and images, is evolving into a comprehensive platform where any kind of community - scientific, media, entertainment, etc - can publish knowledge. Knowledge is derived from information, thus, in a scientific area it is of utmost importance to make the information available as fast as possible. Along with the web evolution, web development tasks have also evolved. Nowadays, it is easier and faster to develop, test and deploy novel applications. Therefore, it is essential for any researcher to know the existing set of tools that are most adequate to his work. Information visualization is one of the research areas where this awareness is more relevant.
