Andrzej Leszkiewicz is a creator of highly customized and interactive data visualizations using Vega visualization grammar and Deneb custom visuals for Power BI. Andrzej will demonstrate how Deneb and Vega can be leveraged to create advanced custom data visualizations.

Target Audience:

Power BI report developers eager to learn how to create custom data visualizations without learning JavaScript and Power BI visuals SDK. Vega visualization grammar is a declarative language that is relatively easy to learn (it's just a JSON file that describes all visual elements).

Session Level and Prerequisites:

Advanced. If you've already realized that core Power BI visuals limit your data storytelling ideas and you haven't found any existing custom visual that satisfies your requirements, it's time to start using Deneb. Understanding of the JSON format is recommended, and a basic understanding of any programming language will be useful.

Learning Objectives:

You'll learn what kind of possibilities the Deneb custom visual for Power BI and Vega visualization grammar offer and how they can be used to move your data visualization far beyond the limitations of Power BI core and many existing custom visuals. You'll learn how to create simple charts using dozens of Deneb Vega templates, and you'll see how further learning of Vega can help you in creating highly customized data visualizations.
