Description This command instructs PopChart Server to return a text description of the PopChart image (refer to "Displaying 508 Compliant Descriptive Text" in Chapter 8 of the PopChart Server User Guide). It accepts as it's argument a two character language code, which tells PopChart Server which language settings to use.
Currently, the only language available in the standard PopChart Server installation is English (EN).
A text description is not an imageyou should treat it as its own separate web page.
