No matter what your data specialty is (data engineering, data modeling, etc.), in the end, data has to be "communicated" to the users of a Power BI report. Data visualizations are used when communicating data to users. Using Power BI, this can be done quickly because Power BI provides a large number of build-in data visualization types.
Sometimes, these built-in data visualizations are insufficient, whether a particular formatting requirement or a complex visual analytical method is required. But even then, these gaps can sometimes be filled using one of the many custom visuals available. One of my favorite custom visuals is Deneb (probably my most favorite custom visual). Deneb is not built to solve a specific data visualization task like a sunburst chart. Instead, Deneb has packaged two of the most powerful data visualization libraries, Vega and Vega-Lite.

Next to a short introduction to Deneb, Vega, and Vega-Lite, this session explains important concepts like layers (the superpower that allows layering bubbles on top of rectangles) and scales, the mapping of different value ranges or the mapping of a categorical variable like the product to a color. Practical examples and demos from this session, these examples will become available for downloading.

This session addresses every Power BI Report Designer and Power BI Developer who wants to bring their data visualizations to the next level.
