d2-docs VS d3

You're right, d2-docs will be changed to render all diagrams with Dagre or ELK instead.

The docs existed before D2 was open source and we had open source layout options. Sorry about that.

> By the way I've just realised why your github repo does not provide the sources of the diagrams in docs - it would blow your game wide open, once users start asking why they aren't getting the results depicted. And almost no compileable examples, either

Not sure what you mean no compilable examples. Full source of the docs is at https://github.com/terrastruct/d2-docs including all the examples. The first example in the Github repo also had a line "Rendered with the TALA layout engine" so the source was upfront.

> Will you please stop lying? I am not "mad" because something isn't free, but because you're misrepresenting the nature of your D2 language. It is not something that you're making available to benefit community, but a thinly disguised marketing ploy.

We're running a company, we're absolutely interested in making money.

But open sourcing D2 doesn't just help us with user acquisition, it certainly also helps the community in adding another open source alternative in the text to diagram market. And it's good quality code. If we go under, someone else can pickup the torch and fork D2.

And it's incorrect to say that the free engines are not as good. They absolutely are suitable alternatives and do beat TALA in many instances. It's not in our interest to hide the best parts of D2, or else no one would use it. I'd even go as far to say TALA will never be as good as them in many instances, especially when the structure is hierarchical. But that's ok, they all use different algorithms and that's what makes them good in different instances. TALA is specifically for software diagrams, in instances such as if you have many nested containers.

If you can quote a specific piece of text on our GitHub or website, we will change it to make it more clear that D2 is fully open source and TALA is just an optional optimization.

Yes this was done with a combination of GSAP Scrolltrigger https://gsap.com/docs/v3/Plugins/ScrollTrigger/ and https://d3js.org/

d3 - very power visualization library enabling dynamic visualizations. docs

Yep, Evidence is doing good work. We were most directly inspired by VitePress; we spent months rewriting both D3’s docs (https://d3js.org) and Observable Plot’s docs (https://observablehq.com/plot) in VitePress, and absolutely loved the experience. But we wanted a tool focused on data apps, dashboards, reports — observability and business intelligence use cases rather than documentation. Compared to Evidence, I’d say we’re trying to target data app developers more than data analysts; we offer a lot of power and expressiveness, and emphasize custom visualizations and interaction (leaning on Observable Plot or D3), as well as polyglot programming with data loaders written in any language (Python, R, not just SQL).

D3.js: A robust library to visualize your data and create interactive data-driven visualizations.

They are images so it could be any number of things, datawrapper, charts.js, d3.js to name a few options.

I made this interactive visualization that attempts to show the real-time frequency and location of births around the world. A country’s annual births (i.e. the country’s population times its birthrate) were distributed across all of the populated locations in each country, weighted by the population distribution (i.e. more populated areas got a greater fraction of the births). Data Sources and Tools Population and birthrate data for 2023 was obtained from Wikipedia (Population and birth rates). Population distribution across the globe was obtained from Socioeconomic Data and Applications Center (sedac) at Columbia University. Data is processed and visualized at a 1 degree x 1 degree resolution, each of which has a different probability of a birth occurring in a specific time period. D3.js was used to create the map elements and html, css and javascript were used to create the user interface.

When I go to the homepage of types/d3 the only hint for any kind of documentation is what seems to be the main github page of d3. It's highly possible I'm missing something here, so sorry if I am but I can't find any documentation of how you are supposed to type these library objects.
