Project Architecture & Methodology

This dashboard is a high-performance, in-browser analytics engine processing over 25 million user reviews. To construct a complete analytical picture, the raw dataset was enriched via a custom Python data pipeline that fetched real-time metadata directly from the TMDB REST API before compiling the results into highly compressed Parquet files.

The front-end leverages DuckDB-Wasm for lightning-fast, client-side SQL querying and D3.js for reactive visualization. Clicking specific years on the control chart triggers instant dynamic filtering and weighted average recalculations without relying on a remote server.
