Deneb is a certified custom visual, that allows you to create your own bespoke visual designs in Power BI using the declarative JSON-based languages of Vega and Vega-Lite.

One big differentiator between Deneb and the R & Python visuals, is that your designs can interact with Power BI and other visuals on the page using standard features such as tooltips, cross-filtering, cross-highlighting and drillthrough.

Because some of these interactions require thought by you as a designer to implement suitable encodings for their state, this might seem daunting, but it can be very extensible and provide you with options for guiding your users that cannot be achieved using standard visuals.

In this session, we will take a simple visual and look at how we can extend it to be more fully-featured in the context of the report page.

Note that this session assumes some existing knowledge of Deneb and familiarity with JSON.
