## Description - Add `stack` shape. - Add `ordinal` scale. - Add plot docs. <img width="337" height="424" alt="SCR-20251126-puzm" src="https://github.com/user-attachments/assets/eff9e2d0-c13a-449a-b717-9568e0c2f88d" /> ## Breaking change The bar shape `y0` value is now returned for each data item. ```diff - Bar::new().y0(height) + Bar::new().y0(move |_| height) + Bar::new().y0(move |d| d.height) ```
