Carr et al had a similar idea - applied to color encoding - back in the 80s! (From www.jstor.org/stable/2289444, paywalled…)

A 2D binned hexgrid plot with a color encoding that uses hue for the logarithmic order of magnitude and area of a black infill to linearly encode the less significant digits.

The Mosaic architecture for database-backed interactive visualization just hit 1,000 stars on GitHub! Thank you to all who have participated and contributed!

Screenshot from GitHub showing 1k stars for the Mosaic project, an extensible framework for linking database and interactive views.

TFW you have a grand idea only to find it's out of reach. So it goes for my chatbot that meows and purrs.

A webpage that reads "This domain is for sale! CatGPT.com. $220,000 USD."

Love this work! Also related is the Boba project, led by Yang Liu and @kalealex.bsky.social, which includes a variety of multiverse visualization and assessment methods. idl.uw.edu/papers/boba

Authoring and visualizing multiverse analyses with Boba. Users start by annotating a script with analytic decisions (a), from which Boba synthesizes a multiplex of possible analysis variants (b). To interpret the results from all analyses, users start with a graph of analytic decisions (c), where sensitive decisions are highlighted in darker blues. Clicking a decision node allows users to compare point estimates (d, blue dots) and uncertainty distributions (d, gray area) between different alternatives. Users may further drill down to assess the fit quality of individual models (e) by comparing observed data (pink) with model predictions (teal).

Fresh off their group's Nobel prize 🧬‼️, this example from UW graduate students enables evaluation of proteins designed using AI diffusion models. idl.uw.edu/mosaic/examp...

Mosaic v0.12 is out: database-powered scalable, interactive visualization! 📈 One new addition is support for dynamic changes in the backing data. Move between smaller and larger samples to balance speed and comprehensive coverage.
