Mosaic is the future of data visualization. 10M cross-filtered rows with client-side processing. Powered by @duckdb
Chaining LLM calls can improve output quality, but navigating the massive space of task decompositions is challenging. Revisiting the established field of crowdsourcing, we distill strategies for effective LLM chain design and identify opportunities for future research. [1/11]

“Can we get a new text analysis tool?” “No—we have Topic Model at home” Topic Model at home: outputs vague keywords; needs constant parameter fiddling🫠 Is there a better way? We introduce LLooM, a concept induction tool to explore text data in terms of interpretable concepts🧵

The Vega Project is happy to announce the release of version 5.3.0 of the Vega-Altair Python visualization library. This release has been 4 months in the making and includes enhancements, fixes, and documentation improvements from 11 contributors. Highlights in 🧵

Observable Framework 1.3 🆕 integrates @uwdata’s Mosaic vgplot, which can concisely expressive performant coordinated views of millions of data points. observablehq.com/framework/l…

Interact with millions of data points in real-time with Mosaic, now with support for geospatial data. Exploring 1M taxi pickups and dropoffs in NYC:
Chaining LLMs together to overcome LLM errors is an emerging, yet challenging, technique. What can we learn from crowdsourcing, which has long dealt with the challenge of decomposing complex work? We delve into this question in our new preprint: arxiv.org/abs/2312.11681 [1/9]

Join us in congratulating Dr. Leilani Battle for receiving the 2023 VGTC Visualization Significant New Researcher Award at #IEEEVIS. 🏆 👏 @leibatt is honored for her work showing how data exploration systems can slow down, confuse, bias, and even mislead analysts.

Really enjoying playing with @uwdata 's Mosaic, linking @duckdb with @observablehq plot feels so natural and responsive - just a joy

VisText has been a *ton* of work, and 2 yrs of solid effort. So it's exciting to (finally!) be able to talk about it, and it's gratifying to see it featured on @MIT's homepage. Lead author, @bennyjtang, has a great thread w/details below 👇 And I wanted to offer a few thoughts
Chart captioning is hard, both for humans & AI. Today, we’re introducing VisText: a benchmark dataset of 12k+ visually-diverse charts w/ rich captions for automatic captioning (w/ @angie_boggust @arvindsatya1) 📄: vis.csail.mit.edu/pubs/viste… 💻: github.com/mitvis/vistext #ACL2023NLP

Mosaic looks really great! Great to see a viz library thread down to the db level. DuckDB is such a natural choice for something like this. uwdata.github.io/mosaic/
To test Mosaic we developed vgplot, a Mosaic-based grammar of interactive graphics that uses Observable Plot to perform chart rendering. Our initial benchmark studies show order-of-magnitude performance improvements over Vega, VegaFusion, and standard Observable Plot.
