[OC] A visual map of today’s top global news stories, clustered by semantic similarity and colored by AI sentiment analysis

Data Source: Automated hourly reads of RSS feeds from major global publishers (BBC, Reuters, Financial Times, Al Jazeera, TechCrunch, etc.) via a Node.js pipeline.

Tools Used:

• Clustering: Google text-embedding-004 vectors using local Cosine Similarity math to group identical stories.
• Sentiment & Scoring: Gemini-2.5-Flash to assign a -1 to +1 sentiment gradient and a 1-10 global relevance weight.
• Visualization: React and D3.js (specifically d3.treemap with a custom structural override for category sorting).

Interactive Dashboard: You can view the live updating map here: https://newsblocks.org (Note: The layout is fully responsive, and clicking any block reveals the source citations).
