Description:
Currently, the official (built-in) Power BI visuals — such as Waterfall, Combo Chart, Line Chart, and others — are closed-source.
This prevents developers and advanced users from understanding or extending their behavior, even for simple adjustments such as customizing labels (“Total” → “Actual”) or improving formatting consistency.
I would like to propose that all standard / built-in visuals be published as open-source pbiviz projects on GitHub,
in the same way that custom visuals can be.
This would bring several clear benefits:
Enable the community to submit pull requests and improvements to existing visuals.
Increase transparency in how visuals handle data and formatting logic.
Allow organizations to self-customize visuals internally without waiting for product releases.
Encourage consistency and quality across built-in and custom visuals.
Power BI is already a platform that welcomes custom visuals,
so opening the standard ones would be a natural next step toward a more open and developer-friendly ecosystem.
Thank you for considering this — it would greatly empower the Power BI / Fabric community to innovate faster while maintaining compatibility with official visuals.
