wordviz 0.3.3

A lightweight Python package for loading, analyzing, and visualizing word embeddings.

WordViz is a Python visualization library designed for exploring and visualizing word embeddings. Built on top of popular libraries such as matplotlib, plotly, and gensim, WordViz provides intuitive tools for analyzing embeddings through clustering, similarity exploration, and dimensionality reduction, all wrapped in interactive and customizable plots. With WordViz, users can gain insights into the structure of their word embeddings, making it a valuable tool for researchers and practitioners in natural language processing.

This project was created as part of my Bachelor's Degree thesis in Statistics and Information Management with title (translated): "Word Embeddings in Practice: Designing a Library for Visualization and Operations"

Last Version Updates

Fixed

• subset(): replaced len(self.tokens) with self.embeddings.shape[0] as authoritative size source
• Added _require_loaded() guard method with ValueError on uninitialized embeddings/tokens; applied to get_embedding() and subset()
• _validate_file(): fixed guard order, removed inconsistent type coercion, added explicit error for compressed files (.gz, .zip)
• load_from_file(): GloVe conversion temp file written to cache dir instead of cwd
• removed unnecessary dev dependencies
• substituted print() statements with logging for better logging practices

See more about previous changes in CHANGELOG.md

Main Features

• Load and explore pretrained embeddings (e.g., GloVe, FastText)
• Select from a variety of available embeddings
• Visualize embeddings in 2D or 3D with flexible dimensionality reduction options
• Identify and plot the most similar words to a given token
• Visualize clusters of related words
• Interactive plots powered by plotly
• Support for many light and dark themes

Installation

Install the latest version from PyPI:

pip install wordviz

Notes: Python version compatibility

Currently, wordviz is not compatible with Python 3.13, due to limitations of some key dependencies:

gensim, one of the core libraries used by wordviz, does not yet provide official support or precompiled wheels for Python 3.13.

For proper installation installation, we recommend that you create a virtual environment with Python 3.12, or just use uv:

uv init --python 3.12

The package will be updated as soon as the dependencies are compatible with Python 3.13.

Usage

You can load and manage embeddings though the EmbeddingLoader class, and then visualize them with the Visualizer (or Visualizer3D) class.

from wordviz.loading import EmbeddingLoader
from wordviz.plotting import Visualizer

loader = EmbeddingLoader()
loader.load_from_file('path/to/your/embedding/file', 'word2vec')

vis = Visualizer(loader)
vis.plot_embeddings()

You can explore all functionalities through the example notebook provided in the docs/ folder:
