Changelog

0.3.1 - 2026-03-22

Fixes

Switch the frontend hyper-scatter dependency to the published npm package so clean installs and GitHub release builds resolve it without a local checkout.

Notes

This release supersedes the failed 0.3.0 PyPI publish and carries forward the user-facing changes documented below.

0.3.0 - 2026-03-22

Features

Add PCA projection support for Euclidean, Poincare, and spherical visualization layouts.
Add 3D layout support for visualizations, including spherical views and 3D lasso selection.
Add Hugging Face ingestion controls for subset configs, streaming, and configurable shuffle buffers.

Improvements

Preserve stable source indices and requested sample tracking during Hugging Face ingestion.
Expand the demo workflow with ready-made Euclidean, Poincare, spherical, and PCA layouts.

Breaking Changes

Replace CLI --geometry with repeatable --layout flags such as --layout euclidean, --layout poincare, and --layout spherical.
Replace Dataset.compute_visualization(geometry=...) with Dataset.compute_visualization(layout=...); bare spherical layouts now resolve to 3D.
