Feature summary:
When clicking on a chart embedded in a Wikipedia article, the user should be taken to the full-resolution .chart view on Wikimedia Commons, just like when clicking on any Wikipedia image. It would display the chart with a more detailed axis scale. It can potentially include interactive features in the future such as zoom-in for further details, and user curve-selection, similar to ourworldindata.org. From there, users could also access the underlying data table, as proposed in T382806, where the original data sources are listed.

Use case(s):
Charts can be kept small and space-efficient in the article itself, improving overall page readability and the overview of chart context. Only those interested in the details need to open the full chart. For example, charts embedded in infoboxes or galleries are intentionally small to avoid dominating the layout (and should not be too tall, as per T397009). While this improves the reading experience, it limits the ability of the most interested readers to perceive fine details or effectively compare trends. Users who wish to explore the data in more depth must currently navigate manually to the Commons .chart or .tab page—if they even know it exists, or editors must manually add links.

Benefits:

• Makes Wikipedia charts more comparable to graphs at successful statistical platforms like Our World in Data

• Improves access to detail without overwhelming the article layout.

• Supports accessibility by giving users control over how much detail to explore.

• Enables future interactive features (e.g. zooming, curve toggling) in the full view.

• Strengthens transparency and verifiability by connecting charts to their sources.

• Creates a clean reader experience while still supporting data exploration for advanced users.
