Embedding Atlas

Embedding Atlas is a tool that provides interactive visualizations for large embeddings and their metadata. You can visualize, cross-filter, and search across your data.

For embeddings

• 🏷️ 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.

• 🚀 Smooth performance at scale: Up to a few million points, powered by WebGPU.

For any tabular data

• 📊 Linked dashboards & cross-filtering: Standard chart types (bar, line, bubble, count plot, eCDF) plus a composable chart spec for building custom charts like heatmaps and average-line overlays. Charts can be configured to cross-filter.

• 🧩 Multimodal data support: Built-in viewers for text, image, audio, numeric, categorical, and time columns.

• 🤖 AI agent access via MCP: AI agents can query the schema, run SQL, create charts, and capture screenshots via Model Context Protocol.

Get started

To use Embedding Atlas with Python:

pip install embedding-atlas

embedding-atlas <your-dataset>

In addition to the command line tool, Embedding Atlas is available as a Python Notebook (e.g., 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:

npm install embedding-atlas

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

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

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