The latest version of the tool makes significant use of your computer's own resources for generating result tables and graphs.  Most modern systems should function without problems, but very old computers may be unable to use the data tool.  Along these lines, the data tool also transfers non-trivial amounts of data over the Internet while in use.  High-speed service (cable, DSL, etc.) is recommended.
