Beijing has introduced new controls on the export of several critical minerals and magnets amid an escalating trade war with Washington. These materials are vital for the production of a range of technologies, from cars to missiles. According to the New York Times, exporters must apply to the Ministry of Commerce for special export licenses, with the process anticipated to be lengthy, risking stockpiles running low.

Data from the United States Geological Survey (USGS) shows that China is the world leader for rare earth reserves. With 44 Mt of known reserves of rare earth oxides (REO) in 2024, it is home to nearly half of the world’s total known reserves (90+ Mt). By contrast, the U.S. has just 1.9 million tonnes of rare earths and is highly dependent on China for imports of these elements. These figures reflect the reserves that could be economically extracted or recovered as of 2024.

Global mine production increased from 376,000 tonnes of REO equivalent in 2023 to 390,000

Many visual models have been conceived and identified in the past several years, but their production is difficult for non-technical users and coding knowledge and a significant amount of time is still required to master the libraries and the tools that allow to create them.

What makes RAWGraphs different from other data visualization tools?

1. No fee and no registration required. RAWGraphs is open and free for everybody

[...]

2. RAWGraphs doesn’t store data.

Even though RAWGraphs is a web app, the data you insert will be processed only by the web browser. No server-side operations or storages are performed, no one will see, touch or copy your data.

3. Open outputs optimized for your design process.

RAWGraphs allows you to export your visualizations in .svg. [...]

I learned about it from this article: https://gijn.org/stories/four-free-c

The Top 4 Countries by rate:

1. India 26%
2. China 18%
3. USA 5%
4. Pakistan 4%

This is only accounting for tracked diabetes, so some of the areas might have larger numbers.

:: Additively weighted Voronoi diagram ::

I wrote this implementation many years ago, but I feel it didn’t receive the recognition it deserved, especially since it was the first freely available. So, better late than never—I’d like to present it here. It’s an algorithm for computing the Weighted Voronoi Diagram, which extends the classic Voronoi diagram by assigning different influence weights to sites. This helps solve problems in computational geometry, geospatial analysis, and clustering, where sites have varying importance. While my implementation isn’t the most robust, I believe it could still be useful or serve as a starting point for improvements. What do you think?
