DANIEL MARSH-PATRICK (Principal Data Analyst, Discover EI) - Deneb: An Alternative Approach for Custom Visual Development

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 already have experience 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 tailor-made designs.

Vega-Lite is a "visualization 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, Daniel 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.

Daniel Marsh-Patrick is extremely passionate about the Microsoft BI stack, particularly Power BI, and has been delivering Power BI solutions since 2014.
