An example of Perspective using DuckDB WASM as a virtual server backend via the DuckDBHandler adapter.

Instead of using Perspective's built-in WebAssembly query engine, this example demonstrates how to use DuckDB as the data processing layer while still leveraging Perspective's visualization components. The DuckDBHandler translates Perspective's view configuration (group by, split by, sort, filter, expressions, aggregates) into DuckDB SQL queries, enabling Perspective to query data stored in DuckDB tables.

This example loads the Superstore sample dataset into a DuckDB table, then creates a Perspective viewer that queries the data through the DuckDB virtual server. A separate log viewer displays the SQL queries being generated in real-time, along with a timeline chart showing query frequency.
