Graphics packages

Grandalf computes node coordinates and routes edges for graph layouts using Sugiyama hierarchical or force-driven algorithms, then leaves the actual drawing to your graphics toolkit of choice.

However, dormant maintenance (last release January 2023) means you should not expect bug fixes or updates; use it only if the current feature set meets your needs and…

Provides a collection of video workflow templates and media assets for use with ComfyUI, a node-based interface for generative AI.

Provides Pixar's Universal Scene Description (USD) core libraries for encoding, storing, and exchanging 3D geometry, shading, and lighting data between content creation applications.

Viser is a Python library for 3D visualization and interactive GUI building, combining 3D scene rendering with web-based controls accessible over SSH.

Install it if you need interactive 3D graphics with web-based access, especially for remote or headless environments.

Renders data in DVC plots format into Vega visualizations and generates HTML or Markdown reports containing multiple plots.

Packages redistributable ANGLE graphics libraries (libEGL and libGLESv2) as Python wheels for Windows, Linux, and macOS, extracted from Electron releases.

Install only if your application or framework actually requires ANGLE libraries; otherwise it adds unnecessary size.

Adds interactive point-selection cursors to Matplotlib plots, allowing users to click on data points and retrieve their coordinates and values.

meshcat is a Python interface to a browser-based 3D WebGL viewer that lets you remotely control and visualize 3D geometries, scenes, and transformations via a scene graph.

Converts Vega-Lite chart specifications to static SVG or PNG images, or to Vega specifications, with no external dependencies.

Supervision provides utilities for loading, annotating, and processing computer vision datasets and model outputs—detection, segmentation, and classification results from any model framework.

Install it if you work with detection, segmentation, or classification models and want to avoid reinventing dataset utilities.

Generates barcodes and QR codes as image objects by wrapping the BWIPP library and Ghostscript, supporting QR codes, Aztec, PDF417, Code128, Code39, and many other barcode types.

The main gotcha is the external Ghostscript dependency and known rendering quirks with older Ghostscript versions—verify compatibility with your target Ghostscript…

Willow provides a unified API for image manipulation across Pillow, Wand, and OpenCV, automatically converting between libraries as needed for operations like resizing, cropping, face detection, and format conversion.

svgelements parses SVG files and provides geometric objects (Path, Matrix, Color, Point, etc.) that conform to the SVG specification, enabling robust manipulation of SVG data as geometric structures.

However, it is dormant—last release was 2023-08-17—so expect no active maintenance.

Python wrapper that exposes SoX audio processing capabilities—trimming, effects, format conversion, and concatenation—via a Transformer and Combiner API.
