An outline of this training course
Deneb is a new certified custom visual available in Power BI that allows the use of the Vega-Lite JSON-based language to describe a visual in full code. Vega-Lite is a declarative language, not an imperative one, in that it describes what a visual should do rather that how it should do it.
Vega-Lite has been around for a while and is a well-established grammar for interactive graphics.
The Deneb custom visual allows visuals to be coded in Vega-Lite to use data from within Power BI files. Deneb further is fully integrated with Power BI in that it responds to the selections made in other Power BI visuals (for example, slicers) and adjusts the data displayed accordingly.
The course is composed three main sections as follows:
- Theory - general descriptions of some of the features of the Deneb visual and the Vega-Lite language
- Practice - specific characteristics of some common visual types in Vega-Lite, and
- Examples - a few illustrative showcases of start-to-finish Deneb visuals
The standard visuals in Power BI don't cover all analysis/insight situations, and Deneb gives the author the ability and flexibility to create just about any visualization using the well-established Vega languages for interactive graphics.
An Introduction to Deneb: Declarative Visualization in Power BI is an intermediate-level course created for those who want finer-grained control over the display of their visualizations than that provided by the standard visuals in Power BI; those who want to create visualizations not possible (at this time, at least) with the standard Power BI visuals; and those who have a preference for a full-code experience when creating and adjusting visualizations.
Details of what you will learn during this course
