Geographic Hierarchies & Computed Column Builder
Features
- Explore your geography as a hierarchy. Geographic hierarchies let you define nested levels over a location column, from broad regions down to fine-grained areas, and explore them as a zoom-banded choropleth, one level at a time. The hierarchy is versioned alongside the rest of your dataset, so changes show up in version diffs.
- A visual builder for computed columns. Compose expressions from a large library of functions: string, date and time, binning, membership, and mapping operations, plus reductions over list- and struct-valued columns. Nest expressions inside one another and pass other columns as arguments, where earlier you could only supply fixed values.
- Dark mode. The whole app now follows a dark theme you can switch on from anywhere.
- Cmd/Ctrl-click the distribution chart legend to compare any set of series at once, with a hover preview of the entry you're pointing at.
Improvements
- The distribution chart subtitle now shows the active filter definition on hover.
- Large datasets, model lists, and geographic maps load faster.
Fixes
- Distribution charts no longer fail to load for multi-partition columns, no longer strand on a canceled recompute, and recover cleanly when a cold recompute runs long.
- Editing a partition keeps its subgroups intact.
- The filter edit dialog now shows and lets you define field groups.
- The logs page holds its scroll position, and you can copy text from expanded rows.
- Fixed permission errors that could block dataset creators from merging their default branch or wrongly deny access when an optional attribute was missing.
