// - The function must accept a CSV string and a configuration object: { filterColumn: string, filterValue: any, groupBy: string, aggregateColumn: string, operation: 'sum'|'avg'|'count' }.

// - You MUST use dynamic import() to load one or more libraries from a CDN for CSV parsing and data manipulation.

// - Parse the CSV, filter rows where filterColumn equals filterValue, group by groupBy column, and perform the specified aggregation.

// - Return an array of objects with the groupBy value and the aggregated result, e.g. [{ department: 'Engineering', result: 90000 }].`,
