XML/SWF Charts is a simple, yet powerful tool to create attractive charts and graphs from XML data.

Create an XML source to describe a chart, then pass it to this tool's flash file to generate the chart. The XML source can be prepared manually, or generated dynamically using any scripting language (PHP, ASP, CFML, Perl, etc.)

XML/SWF Charts makes the best of both the XML and SWF worlds. XML provides flexible data generation, and Flash provides the best graphic quality.
