- Downgrade minimum traitlets version to fix use with Colab. #687
- Fix using
TripsLayer.from_movingpandaswith numpy v2.
- Fix import when pandas not installed.
- New
TripsLayerfor animating moving objects, which integrates with MovingPandas. See the Air Traffic Control example and the MovingPandas integration example. - New
ColumnLayerfor rendering extruded cylinders. See the newColumnLayerexample. - Removed required dependencies!
geopandas,pandas,shapely,pyarrow,matplotlib, andpalettableare now optional dependencies. Lonboard will still work out of the box with them, but they aren't required to use Lonboard. This gives Lonboard a smaller footprint and makes it easier to use in environments such as Pyodide. - You can now draw bounding boxes on the map. This is exposed as the
selected_boundsattribute on theMapobject, stored as a two-dimensional bounding box(minx, miny, maxx, maxy). - Improved documentation
- How to use Lonboard in pyodide, a Python environment that is fully running in your browser.
