#TALA. Great layout engine for text to #diagrams used by #D2 and it is now #FOSS.

> TALA is a novel autolayout algorithm designed with software architecture diagrams in mind. This means it's primarily an orthogonal layout engine, which more closely matches what you might find on whiteboards, rather than the DAG-based ones that grow in one direction. It blends ideas from different graph-drawing research papers (cited in source code) along with original techniques to achieve aesthetic diagrams. It considers multiple objectives of "aesthetic", including symmetry, median distance, flow, clustering of like nodes, and much more.

https://d2lang.com/blog/tala-is-open-source/

One of my favorite open source tools, #D2Lang aka #D2 is now under #HackClub! This makes it a fully #FOSS and #nonprofit project. Thank you Alex for making this awesome tool available for everyone in the long run!

I think on paper a lot and I often ask people what kinds of diagrams and doodles they use for thinking. You get different answers from people in different fields, and if you ask people in political theory or international relations they will say, "If you like conceptual diagrams you have to read Dan Deudney."

So at long last I am reading Dan Deudney. (Well, I am looking at the pictures lol.) This is chapter one of Bounding Power and I am in diagram heaven!

Two #diagrams of #Words from Quran Surah ashShu’arah 26, The Poet.

Discussed Venn diagrams with a couple of friends this morning, especially in the context of illustrating the utility of including all 3 or 4 of a specific set of design principles when creating certain kinds of things, and learned about the difference between Venn diagrams and Euler diagrams.

In short:
* a Venn diagram shows ALL possible relationships between different sets
* an Euler diagram shows only some relationships between different sets, typically focused on conveying relevant or the more important relationships

If you want to dive into their history and why these differences matter, bookmark (or open new tab) this Scientific American article to rabbithole later:
* https://www.scientificamerican.com/article/venn-diagrams-history-and-popularity-outside-of-math-explained/

In pop culture and media, nearly any diagram of overlapping circles with labeled regions is (errantly) referred to as a “Venn diagram”.

This is imprecise at best, outright incorrect in many cases, especially diagrams of four circles.

A classic example is the “Ikigai” diagram:


Many (examples below) call this a Venn diagram. It is not a Venn diagram. It is an Euler diagram.

The Ikigai diagram fails to express two specific relationships between different sets, the two that contain opposing side circles but neither of the other two. The missing Ikigai sets relationships in particular:
1. only “you are good at” AND “the world needs” (with neither of the other two)
2. only “you love” AND “you can be paid for” (again with neither of the other two)

If you Google web search for "examples of four circle venn diagrams", Gemini gets this wrong:


And so do the majority of articles that Google shows in top results (which I’m not helping by linking here, but hey it’s Google’s job to fix its search quality, not mine. I was able to use Internet Archive links for two of them at least.)
* https://web.archive.org/web/20260823204717/https://boardmix.com/knowledge/4-circle-venn-diagrams/
* https://miro.com/templates/4-circle-venn-diagram/ (Miro’s own top template there is wrong, though others have contributed proper 4 set Venn diagrams)
* https://web.archive.org/web/20260823205434/https://www.istockphoto.com/illustrations/venn-4-circles-diagram
* https://www.educationworld.com/tools_templates/EW_venndiagram_4

This has interesting implications for expertise and trust.

Clearly by this one example search result, we cannot trust the expertise of "design tool" websites (boardmix, miro), nor stock photo websites.

Nor can we trust educationworld as a place to be educated.

Nor can we trust Google Search (or Google Gemini) to surface expertise above popular misconceptions.

Perhaps a good example of when to use Wikipedia search instead of Google (or other generic) web search.

Personally I generalize this example to “all proper nouns”, that is:

* Wikipedia search proper nouns instead Google or other general web searching.

You can make this more convenient by setting up “w” as a search shortcut for Wikipedia: https://tantek.com/2024/287/t2/setup-search-shortcuts-firefox
