Data visualization, also known as dataviz, is a data science discipline that uses graphical tools to translate large amounts of data into understandable visuals. It is undergoing a revolution in 2025, driven by generative AI and immersive experiences. Tools like Tableau and Power BI are no longer sufficient: companies are now adopting solutions like Pyramid Analytics, which integrates practical advice in natural language.

Key trends include augmented reality to visualize geospatial data in real time. For example, Nike optimizes its inventory with AI-generated predictive charts. Low-code is also gaining ground, with platforms like FineBI allowing dashboards to be created without technical skills.

Generative AI is transforming data storytelling. Chatbots like ChatGPT analyze data in natural language, such as: “Show me sales by region as an interactive map.” This automation frees up time for strategic analysis.

DataViz is no longer a static report, but a dynamic conversation. Certification training programs, such as those offered by DataScientest, now include modules on generative AI and 3D visualization.

Finally, ethics are becoming central. With the GDPR and the AI ​​Act, companies are looking for analysts capable of ensuring the transparency of visualizations. The DataViz of tomorrow will need to combine technological power and responsibility.
