Explore the intersection of domain-specific languages (DSLs) and program synthesis in this 38-minute conference talk from Strange Loop 2013. Delve into the development of Superconductor, a browser-based language for massive interactive visualizations, which combines end-to-end parallel DSLs and a synthesis DSL for parallel layout. Learn how these innovative approaches enable real-time interactive visualizations of hundreds of thousands of data points with high-level parallelization control. Discover the potential of combining explicit and automatic parallelization through "schedule sketching" and gain insights into the architecture of Superconductor, its flexible layout DSL, and the application of synthesis in data science and beyond.
