uwdata/mosaic v0.6.0

on GitHub

This release adds support for non-linear scales across binning methods, both in gridded marks like raster, and for the bin transform. It also improves marks that use gridded data, such as density, raster, and the new heatmap convenience mark.

Breaking Changes:

This release renames some of the options for density/contour/raster marks and adjusts their defaults. This simplifies some naming and usage, and better aligns with the underlying Observable Plot library.

• binType is now interpolate. The "normal" option value is now "none".
• binWidth is now pixelSize.
• binsX is now width.
• binsY is now height.

Changelog:

• Breaking: Rename options for density/contour/raster marks, change defaults.
• Add support for non-linear scales (log, symlog, sqrt) to pixel-level binning methods.
• Add support for non-linear scales (log, symlog, sqrt) to the bin transform.
• Add SQL scale transform utilities to the mosaic-sql package.
• Add richer option support to raster mark, including gridded ordinal data alongside numeric data.
• Add heatmap mark, a raster mark with convenient defaults for density estimation.
• Add additional plot attributes for scale transforms.
• Add more SQL transforms to the declarative specs.
• Update mark implementations to use improved binning.
• Update density1d example spec to use a log-scaled domain.
• Update examples, including new Observable latency example.
• Update documentation.
• Update dependencies, use DuckDB v0.10.0.
• Fix range transformation bug in DataCubeIndexer.
• Fix filter range bug in DensityLineMark.
• Fix M4 optimization bug in ConnectedMark (line and area).
