Opinion | The A.I. Disruption We’ve Been Waiting for Has Arrived

Nice opinion piece on the state of ai coding

There are 10.990 municipalities in Germany.

From Berlin to the smallest municipality. All their names are shown in this map. The 50 largest cities’ names appear one after the other, after that they appear in chunks of increasing size.

The distribution of the world's wild land mammal biomass Our World in Data Biomass is the total weight of each animal group. It's calculated by multiplying an estimate of the total number of individuals by their average mass. Shown is each group's share of global wild mammal biomass on land. Rodents (16%) Squirrels, mice, beavers Even-hoofed mammals (49%) Deer, boars, warthogs, camels, hippos and giraffes Odd-hoofed mammals (1%) Rhinos, zebras, wild horses Bats (7%) Elephants (8%) Marsupials (7%) Kangaroos, koalas, wombats Rabbits and hares (1%) Primates (4%) Monkeys, apes Carnivores (3%) Lions, tigers, bears Other (4%) e.g. pangolins, hedgehogs, sloths Note: Wild mammal biomass estimates come with substantial uncertainty; some groups have poor population records, and are therefore estimated based on modelling from factors such as the range size of particular animals, and extrapolations of densities from more localized studies.

Loved this opinion piece calling for algorithms that support humans instead of advertisers. Create art not content

For some weird reason the link opens including the ! breaking it

Do you mean logging in to the conference site? That one I don't control 🤷‍♂️. Cc @ieeevis.bsky.social

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

Awesome!

Very interesting what you can do now with Visual Studio Code + Github Copilot Agent mode. Nice tutorial here by @burkeholland.bsky.social www.youtube.com/watch?v=duty...

A brief history of JavaScript | Deno In 30 years, JavaScript went from being a little scripting language to one of the world's most popular. Here are key moments to show how it has evolved and where it is headed.

What a great summary history of JavaScript by deno deno.com/blog/history...

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 📲

Glad you liked it! I'm adding a new option for creating the selection of papers you don't want to miss... Stay tuned 😀

Minimalism and the absurdity of the data-to-ink-ratio How much minimalism is too much minimalism? I explore this question and propose the most minimalist, highest scoring data-to-ink ratio on a visualization ever made as a thought piece. Why? Well novice...

I wrote about the data-to-ink ratio and a new game I've invented called "ink golf" for data visualization.

I hope you enjoy:

A new way to make graphs more accessible to blind and low-vision readers Designed to help blind and low-vision readers understand graphics, the “Tactile Vega-Lite” system from MIT CSAIL converts data into a standard visual graph and a tactile chart. Accessibility standards...

Tactile charts are an important tool for conveying data to blind and low vision people via embossed paper. However, tactile charts require high levels of time and expertise to design.

I noticed the SOM from the post, but haven't had a chance to explore it yet. I'm very curious about it and also about your querying.

BTW. Did you clustered on the embedding or the D.R. space? I tried clustering for #ieeevis with disappointing results johnguerra.co/viz/ieeevis2...

Very nice @ray-zou.bsky.social 👏

You beat me to it jajaja 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:
