Embedding Atlas

Embedding Atlas is a tool that provides interactive visualizations for large embeddings. It allows you to visualize, cross-filter, and search embeddings and metadata.

Features

🏷️ Automatic data clustering & labeling: Interactively visualize and navigate overall data structure.
🫧 Kernel density estimation & density contours: Easily explore and distinguish between dense regions of data and outliers.
🧊 Order-independent transparency: Ensure clear, accurate rendering of overlapping points.
🔍 Real-time search & nearest neighbors: Find similar data to a given query or existing data point.
🚀 WebGPU implementation (with WebGL 2 fallback): Fast, smooth performance (up to few million points) with modern rendering stack.
📊 Multi-coordinated views for metadata exploration: Interactively link and filter data across metadata columns.

pip install embedding-atlas

embedding-atlas <your-dataset.parquet>

In addition to the command line tool, Embedding Atlas is also available as a Jupyter widget:

from embedding_atlas.widget import EmbeddingAtlasWidget

# Show the Embedding Atlas widget for your data frame:
EmbeddingAtlasWidget(df)

Finally, components from Embedding Atlas are also available in an npm package:

1

npm install embedding-atlas

import { EmbeddingAtlas, EmbeddingView, Table } from "embedding-atlas";

// or with React:
import { EmbeddingAtlas, EmbeddingView, Table } from "embedding-atlas/react";

// or Svelte:
import { EmbeddingAtlas, EmbeddingView, Table } from "embedding-atlas/svelte";

Development

This repo contains multiple sub-packages:

Frontend:

packages/component: The EmbeddingView and EmbeddingViewMosaic components.
packages/table: The Table component.
packages/viewer: The frontend application for visualizing embedding and other columns. It also provides the EmbeddingAtlas component that can be embedded in other applications.
packages/density-clustering: The density clustering algorithm, written in Rust.
packages/umap-wasm: An implementation of UMAP algorithm in WebAssembly (with the umappp C++ library).
packages/embedding-atlas: The embedding-atlas package that get published. It imports all of the above and exposes their API in a single package.

Python:

packages/backend: A Python package named embedding-atlas that provides the embedding-atlas command line tool.

Documentation:

packages/docs: The documentation website.
