Reviewer scorecard
“10-100x faster than pandas with better syntax. Lazy evaluation and parallel execution are game-changing for large datasets.”
“Observable Framework for data apps is excellent. Static site generation from data notebooks is the right approach.”

“Observable Framework is the sleeper hit — build data dashboards as static sites with SQL and JavaScript.”
“Polars is replacing pandas for performance-sensitive work. Rust-powered data tools are the future.”
“The best platform for creating interactive data visualizations. D3 integration and the reactive model are powerful.”
