Leaflet VS d3

9. Leaflet

Leaflet is the most famous open-source map library, with lots of plugins. 2 of them are used to animate a marker on the map:

Leaflet stands out as one of the top open source JavaScript libraries for crafting interactive maps. Optimized for both mobile and web devices, it is relatively small (around 42KB) and offers a ton of features, plugins, and a straightforward API. It works across all browsers and platforms.

Finding maplibre 'better' was more valid at the time than today, and is also subjective. The creators and maintainers of both libraries have done some great work (and are still doing so).

Back in January 2022, the stable version of leaflet, v1.7.1, was from September 2020, and was affected by some small bugs degrading the user experience. Although the release of following version seemed close, there was no clear schedule for it, and I had concerns about how maintained the library would remain.

As of today, the bug from 2015 where there is some white space between map tiles on fractional zoom levels [0] is still open.

Also, leaflet was a pain to integrate in Svelte Kit framework, because it depended on `window` and-or `document`, not available at server side.

Maplibre, on the other hands, with a feature set roughly equivalent to Leaflet, benefited from much more frequent releases, and seemed more stable across browsers and devices. It was also easier to make it work in Svelte kit.

For a personal project, I had to use Leaflet with Svelte, and I faced some problems during development.

Do anyone have any workaround on how to get leaflet js to work inside notion, either as an embed or as code, or widget? https://leafletjs.com/

None of those things are what most in the GIS space would consider "complex", so you could go with any of the options you selected. For lightweight maps, I like Leaflet

I have a special place in my heart for Leaflet and it’s documentation: https://leafletjs.com

Its suppose to be free: like with map data providers there's Leaflet, OpenStreet Maps and many more which are all for free.

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.
