Welcome !
If you’ve landed here, chances are you came from my LinkedIn. This is a quick recap of a fun little solo project I did to explore the most in-demand skills in the Data & AI job market in France, as of May 2025.
It was a simple end-to-end (E2E) project, meaning I did everything myself: from gathering the data to exploring it and building the visualizations.

The idea
Turn the chaos of job listings into a clear, visual map of the Data & AI landscape :
- Scrape 2,500 job postings using keywords like “data”, “AI”, “ML”, “Power BI”, etc.
- Feed it all to a well-prompted LLM to turn messy job descriptions into clean structured data.
- Visualize the results as a galaxy of skills, where connections and gravity fields emerge naturally.
Quick explanation of the result
Once cleaned and structured, the data practically organized itself. Visualizing it as a skill galaxy revealed not just which tools and roles dominate the market, but how they connect and cluster in real-world job offers.
Each node represents a skill. The bigger the node, the more frequently it shows up in job postings. The thicker the links, the more often two skills appear together (think SQL & Power BI).
From this emerges a really coool structure with three main constellations:
- At the top, the Data Science zone, orbiting around the star that is Python.
- Bottom left, the Data Engineering universe, where a DevOps constellation cuts across the map.
- On the right, the Business Intelligence territory, lit up by a SQL supernova, gently fading into quieter yet essential areas like Governance and Product.
What started as raw text became a map of the Data & AI ecosystem ! Alive with connections, gravity, and meaning 🌌.

Cool, okay, but how did you build that ?
