The CHI Papers Explorer is back for #CHI2026! As every year, you can explore all 2,769 papers using semantic search. Type any topic, see papers ranked by relevance, and build your schedule. Try it and please share with everyone heading to Barcelona: johnguerra.co/viz/chi2026P... @chi.acm.org #HCI

My #IEEEVIS 2025 paper explorer is live! 🎉 👉 johnguerra.co/viz/ieeevis2... 👈 An interactive #dataviz to explore 300+ papers by similarity. Perfect for: ✨ Discovering papers related to your interests ✨ Planning which sessions to attend ✨ Creating your own paper list (new!) Pls help me distribute it

To help me keep track of the #chi2025 papers that I don't want to miss I made this quick prototype: 👉🏼 johnguerra.co/viz/chi2025P... 👈🏼 * Search by semantic content * Aggregate multiple searches * Find papers by authors, institutions, types, awards... * Quickly check where to go from your 📲

Here is my #chi2025 paper explorer. Visually explore papers by similarity, search for an specific topic or even find what specific sessions to attend. Please let me know what you think! #dataviz @chi.acm.org 👉🏼 johnguerra.co/viz/chi2025P... 👈🏼

Many kudos to the vispubdata.org team for keeping the dataset up to date. As a thank you note, here is how easy it is to build the impressive @drpi.bsky.social's 2.5 @ieeevis.bsky.social ego-network of co-authorships: 🙏🏻 johnguerra.co/viz/visPubNe... 2/2

Do you want to explore your own @ieeevis.bsky.social co-authors and citations networks? Check out my latest #dataviz 👉🏼 johnguerra.co/viz/visPubNe... 👈🏼 I'm showing the @northeasternu.bsky.social VIS Lab professors network, and the overall authors with more than 20 collaborations. Create your own!

Do you want to animate a @vega-vis.bsky.social vega-lite or @observablehq.com Plot chart? Here is a quick experiment that might help you that animates between two SVGs. Let me know what you think! #dataviz. 👉🏼 observablehq.com/@john-guerra...

How many attributes can you visualize in one chart? A little experiment on multi dimensional #dataviz that I made for a talk 👉🏼 observablehq.com/@john-guerra...

One of my students wanted to use an online image on her page. I challenged her to recreate it with code... and couldn't resist doing my own #generativeArt experiment 😝 observablehq.com/@john-guerra...

I created an interactive co-authorship network #dataviz of @ieeevis.bsky.social researchers 👉🏼 observablehq.com/@john-guerra... 👈🏼 This visualization explores the connections between researchers who have co-authored papers at IEEE VIS 1990-2023 Built with reactivewidgets.org and @observablehq.com

To emphasize that land area is not that important for elections, I created this US election results visualization story johnguerra.co/viz/USElecti... up to 2020 data... Waiting to get access to this year's results
