## What it is
Earth is a JavaScript web application that visualizes global weather, wind, ocean currents, and related atmospheric conditions on an animated interactive globe. It powers the well-known earth.nullschool.net site and renders data from sources like NOAA GFS using D3 and TopoJSON in the browser.

## Use cases
- visualize global wind patterns on an interactive globe
- display animated ocean currents and wave data
- build a custom weather map web application
- explore atmospheric data like temperature, pressure, and aerosols visually
- render geospatial vector data with D3 and TopoJSON
- create an animated globe of real-time forecast data

## When to choose
- you want a browser-based animated globe for weather or ocean data
- you need a proven open-source codebase to customize for your own geospatial visualization
- you want to learn browser-based D3/Canvas geospatial rendering techniques

## When to avoid
- you need a maintained library with active support - development is sporadic and it is a personal project
- you need a reusable npm library or API rather than a self-contained application
- you need server-side rendering or mobile-native apps

## Facets
- artifact type: application
- maturity: maintenance
- function: data-visualization, web-scraping, animation
- domain: data-visualization, weather, web-development
- platform: browser
- tags: weather-visualization, wind-map, d3, topojson, gfs-data, ocean-currents, canvas-animation, maps, nodejs, web-server
