What widgyts is
widgyts is a free, web-based Jupyter widget package for interactive exploration of yt datasets and mesh-based data. Its pan-and-zoom widget uses WebAssembly and renders in the browser after data reaches the notebook. DatasetViewer presents dataset parameters, fields, and other metadata, and includes a simple 3D grid viewer for adaptive mesh refinement datasets. For variable meshes, ImageCanvas, FRBViewer, and ColorMaps widgets provide interactive views, with traitlets linkable between widget instances. Importing widgyts adds display support to yt Slice and Projection objects. Particle viewing is preliminary: particles must be added explicitly and this currently works only with AMR datasets. Documentation covers installation from PyPI with pip or from source, lists ipywidgets, ipydatawidgets, and yt as minimum dependencies, and provides a JupyterLab extension route with JupyterLab 0.35 or newer recommended. Saved DatasetViewer data should persist in notebooks and appear on nbviewer. PyPI lists version 0.5.1, released April 14, 2023, under BSD-3-Clause, with The yt Project as author.
Who it suits
It suits Jupyter users exploring yt or mesh-based datasets interactively in a web notebook. It is also relevant to users needing linked mesh widgets or basic AMR grid views.
What it does well
- Free plan available
- Interactive pan-and-zoom browser widget
- Dataset metadata and 3D AMR grid view
- Linked mesh visualization widgets
- Supports yt Slice and Projection display
What to know first
- Particle viewing is preliminary
- Particles require explicit addition
- Particle support currently limited to AMR datasets
- Listed release is from April 14, 2023
Verdict
widgyts brings interactive yt and mesh visualization into Jupyter notebooks through browser widgets. Its AMR particle support is still limited, so users needing that capability should account for the stated restrictions.
