## What it is
A WebGL-powered library for visualizing wind data as GPU-accelerated particle animations, capable of rendering up to 1 million particles at 60fps. It includes tooling to download and convert ECMWF weather data (via ecCodes) into PNG/JSON wind data files.

## Use cases
- visualize global wind patterns on a map
- render animated wind particle flows in the browser
- build a weather map like earth.nullschool.net
- display wind speed and direction from GRIB weather data
- create GPU-accelerated particle simulations for geospatial data

## When to choose
- you need high-performance wind or flow-field visualization on web maps
- you want GPU-based particle rendering at 60fps
- you have GRIB weather data you want to visualize as animated particles

## When to avoid
- you need a general-purpose mapping library rather than a specialized wind visualization
- your project requires non-WebGL environments or older browsers
- you need regularly updated weather data pipelines without custom scripting

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, simulation, graphics, gpu-computing
- domain: data-visualization, graphics, weather
- platform: browser
- tags: webgl, particles, wind, gpu-accelerated, map-visualization, maps, web-server, javascript
