I walk through the new Radial Chart type now available as a trial in Tableau Public until June 30th, building one from scratch with Superstore data. I figure it out live, layering subcategory and segment, adding quantity to angle, and showing where the current limitations and bugs lie.

## Key takeaways

- Radial Charts (alongside Sankey Charts) are available in Tableau Public as a trial until 30 June.
- A radial chart behaves much like a layered pie chart: the order of dimensions on Level dictates the order of the rings, and the first dimension drives the colour.
- Put a measure such as Quantity on Angle to size the segments proportionally, otherwise everything renders in equal proportions.
- Labels tend to break and need disabling, and there's currently no way to drop a dimension onto Colour or Detail, so colour control is limited.
- You can already fake a two-level radial chart by layering pie charts at different levels of detail, but the native chart type avoids that hack.
