Summary & Key Takeaways ​

• Simon Willison created an animated transition between two map projections.
• The project shifts from the Mercator projection to the Equal Earth projection.
• GPT-6 Astra (medium) in ChatGPT Work assisted in the development.
• D3.js was used to implement the interactive visualization.
• The tool was inspired by a recent UN vote on the Equal Earth map projection.

Our Commentary ​

Another "vibe-coding" example from Simon, this time with GPT-6 Astra. It's cool to see these LLMs handling complex D3 visualizations. The animation itself sounds fascinating, and it's a great way to explore geospatial concepts. We're seeing a pattern here: LLMs are becoming powerful co-pilots for specific, often visually-driven, web development tasks. It's less about writing boilerplate and more about tackling intricate logic.
