The patent and DBD::Chart cover different grounds. The patent very specifically covers an extension to SQL (including new keywords) to be used to apply a transform on the output of a query. DBD::Chart does not extend SQL — it creates virtual tables instead — and cannot be used to transform the output of queries.

Update: Improved the grammar.
