Building custom visuals in Power BI gives you total control over your scenario and results can be very rewarding. However, there's a high learning curve, particularly if you are not familiar with web development tools and technologies.

If you're already familiar with R and/or Python, Power BI offers visuals with an interface for you to write code in these languages, and these options can help a lot with producing bespoke designs.

Vega-Lite is a "visualisation grammar" developed by the University of Washington Interactive Data Lab. It uses a declarative, JSON-based language that allows authors to build a range of bespoke visual designs with significantly less effort than coding from scratch.

In this session, we will introduce you to the Vega-Lite language via Deneb - a custom visual for Power BI. We will create some example visuals, as well as demonstrate some of the additional integration features with Power BI that aren't currently possible if using R & Python.
