v0.4.1

Changed

• Matrix, ModuleTreeWidget, and ChartSelect now render a small "graduated to marimo core" hint in the cell when instantiated inside a marimo notebook, with a link to the equivalent marimo built-in (marimo.ui.matrix, marimo's built-in PyTorch formatter, and marimo.ui.matplotlib respectively). The widgets continue to work as before in Jupyter and other anywidget hosts.

v0.4.0

Fixed

• EnvConfig no longer syncs configured secret values in its exported anywidget state, preventing marimo static HTML exports from embedding environment-loaded or manually entered secrets.

Removed

• WandbChart widget removed due to a security concern: marimo's static HTML export embeds all anywidget traitlets, which would leak the user-supplied api_key into any exported notebook.

v0.3.5

Added

• Treemap widget: new hovered_path traitlet that updates as the cursor moves over rectangles, allowing Python code to react to hover without requiring a click.

v0.3.4

Added

• Treemap widget: zoomable hierarchical treemap rendered on canvas with hover previews, clickable path navigation, leaf selection, contextual recoloring during zoom, and constructors for direct {name, value, children} dicts, path mappings, records, or dataframes. Ported from the Svelte components in koaning/pytest-duration-insights.
• NestedTable widget: recursive expandable table showing name, summed value, and share of the root total. Shares the same hierarchy shape and from_paths / from_records / from_dataframe classmethods as Treemap.

v0.3.2

Added

• ApiDoc.to_markdown() method to export API documentation as a Markdown string for use in READMEs.
• ApiDoc signature block now has Python syntax highlighting, matching code blocks in docstrings.

Changed

• Moved example notebooks from examples/ to demos/ folder.
• Added infinite zoom (Droste effect) example to the docs gallery.
• Paint toolbar icons: replaced generic pencil icons with a distinct pen (brush) and highlighter (marker) to make the tools easier to tell apart.

v0.2.20

Added

• EnvConfig.get(name, default=None) method for dict-like access that returns a default value instead of raising KeyError.
• Optional variables parameter to EnvConfig.require_valid() to check only a subset of configured variables, allowing some to remain unset.

v0.2.19

Added

• New ChartSelect widget for interactive region selection on matplotlib charts. Supports box and lasso (freehand) selection modes, returns selection coordinates in data space, and includes helper methods (get_mask(), get_indices(), get_bounds(), contains_point()) for filtering data points. Also supports from_callback() factory for auto-updating charts.

v0.2.18

Fixed

• Removed scikit-learn from core dependencies. It was accidentally added as a required dependency but is only used by the optional ChartPuck.export_kmeans() method. Users of this method should install with pip install wigglystuff[test].

v0.2.17

Changed

• Breaking: ChartPuck.from_callback now passes the widget to the draw function instead of scalar coordinates. The signature changed from draw_fn(ax, x, y) to draw_fn(ax, widget), giving access to all puck positions via widget.x and widget.y lists.

Added

• New redraw() method on ChartPuck for manually triggering chart re-renders when external state changes (e.g., dropdown selections). Only available for widgets created via from_callback().
• Added Step, Nearest, Quadratic, and Barycentric interpolation methods to the ChartPuck spline demo.

v0.2.15

Added

• Playwright browser integration tests for SortableList widget, verifying full browser-to-Python round-trip communication. Tests cover rendering, adding/removing/editing items, and Python state synchronization.
• New test-browser optional dependency group and CI workflow for running browser tests with marimo.

Removed

• Removed unused pydantic-ai dependency that was pulling in openai and breaking WASM demos.
