# Deneb: Declarative Visualization in Power BI

Deneb is a certified custom visual for Power BI that lets you create your bespoke visuals right inside Desktop using either the Vega or Vega-Lite visualization grammars. Visuals can be prototyped and iteratively developed using their declarative JSON-based languages, providing a ‘code-like’ experience where you are not constrained to a specific type of chart.

While this methodology is more in line with the inbuilt R & Python visuals, Deneb addresses several shortcomings with those approaches where integration or deployment are concerned—providing support for interactivity, publishing to web and mobile reports, and exporting to PDF—running anywhere a certified custom visual can.

In this session, we will provide a short introduction to the visual and highlight some of the key features.
