## What it is
Mini Tokyo 3D is a real-time 3D digital map of Tokyo's public transport system, visualizing trains, aircraft, and stations live in the browser. It is built as a JavaScript web application with an embeddable viewer and plugin system.

## Use cases
- view live Tokyo train and flight positions on a 3D map
- embed a real-time transit map into a website
- track a specific train or station in 3D
- search transit routes in Tokyo
- explore underground station layouts in 3D
- build custom transit visualizations with plugins

## When to choose
- you need a real-time 3D visualization of Tokyo public transport
- you want an embeddable, interactive transit map for a web page
- you are building a plugin or custom viewer on top of Tokyo transit data

## When to avoid
- you need transit maps for cities other than Tokyo
- you need offline or non-real-time transit data
- you need a general-purpose mapping library rather than a finished application

## Facets
- artifact type: application
- maturity: active
- function: data-visualization, geospatial
- domain: data-visualization, web-development
- platform: browser, cross-platform
- tags: 3d-map, public-transport, tokyo, real-time-tracking, mapbox, trains, transit, maps, real-time, web-server
