## What it is
JSCity is a tool that visualizes JavaScript source code as navigable 3D cities using the Code City metaphor and the three.js library. Folders become districts, files become sub-districts, and functions become buildings whose height and base size reflect lines of code and number of variables.

## Use cases
- visualize a javascript project's structure as a 3d city
- understand code complexity of a large js codebase at a glance
- identify large or deeply nested functions in javascript source
- teach software visualization using the code city metaphor
- explore anonymous vs named function distribution in a project

## When to choose
- you want an intuitive 3D overview of a JavaScript codebase's size and structure
- you are doing research or education in software visualization
- you prefer a self-hosted tool with a Vagrant setup option

## When to avoid
- you need visualization for languages other than JavaScript
- you want an actively maintained tool with recent updates
- you cannot install MySQL or Node.js locally
- you need lightweight static analysis without 3D rendering

## Facets
- artifact type: application
- maturity: maintenance
- function: data-visualization, graphics, parser, developer-tools
- domain: developer-tools, data-visualization, web-development
- platform: cross-platform
- tags: code-city, software-visualization, threejs, javascript-analysis, 3d-visualization, research-tool, nodejs, web-server
