Power BI's visuals are intuitive, highly-polished and look great. They serve many use-cases, but there are those who want to customise further. There are options to go beyond this and some are more involved and complicated than others.

Power BI has inbuilt R and Python visuals that let users write code to produce bespoke visuals inside the application. What if we used this idea to bring a new kind of custom visual to Power BI that could use the concept of a visualisation 'grammar' to build them instead?

In this session we will explore the concept of such a tool, and how we can use it to produce bespoke visuals in Power BI, starting with taking the data we want to work with and using a structural approach to quickly prototype and build a visual as we explore it.
