Deneb is a custom visual for Microsoft Power BI, which allows developers to use the declarative JSON syntax of the Vega or Vega-Lite languages to create their own bespoke data visualizations without having to learn web development.

This is similar to the approaches used for creating R and Python visuals in Power BI, with the following additional benefits:

• Libraries are packaged with the visual, so no additional dependencies on local libraries or gateways for your end-users when publishing reports.
• Specifications are rendered inside the Power BI client, rather than being delegated to another location, typically resulting in faster render times for end-users.
• Built for the web, meaning that it's possible to integrate with Power BI's interactivity features, with some additional setup.

Deneb is a certified visual on AppSource (the Power BI visuals marketplace), is free to use, and open source.
