We describe two prototypical World Wide Web-based tools for visualization of text data. By using the Web, the tools enrich the interaction between the analyst and the data. Both are portable: they are written in Java and run within a standard Web browser. They access data from a very large central data base, instead of requiring that it be downloaded; this leads to signiicant gains in eeciency, as well as in maintenance (timeliness and security) of the database. Decreased performance resulting from use of interpreted rather than compiled code can be mitigated by means of clever programming. One tool, SeeSoft TM , can display thousands of lines of text on a single screen, allowing detection of patterns not discernible directly from the text. The second tool, Live Documents, replaces static statistical tables in ordinary documents by dynamic Web-based documents, in eeect allowing the \reader" to customize the document as it is read.
