## What it is
A TypeScript library for rendering zoomable, animated scatterplots in the browser that scale to billions of points using WebGL and Apache Arrow data tiles. It is the graphics engine behind Nomic's Atlas and is licensed for noncommercial use only.

## Use cases
- visualize a billion-point dataset interactively in the browser
- embed a zoomable scatterplot of millions of embeddings in a static site
- explore large embedding maps like tweet or arxiv visualizations
- render census-scale point data with GPU-accelerated transitions
- host a million-point scatterplot on GitHub Pages

## When to choose
- you need interactive exploration of extremely large point datasets in a web browser
- you want GPU-accelerated grammar-of-graphics transforms and animated transitions
- you can serve data as Apache Arrow feather tiles and want static hosting

## When to avoid
- your project is commercial - the CC BY-NC-SA license forbids commercial use
- you need small-dataset charting where simpler libraries like D3 or Plot suffice
- you need non-scatterplot chart types like bars or lines

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts
- domain: data-visualization, web-development, frontend
- platform: browser
- tags: webgl, scatterplot, apache-arrow, gpu-rendering, quadtree, large-datasets, typescript, web-server, nodejs
