## What it is
Plato is a JavaScript static analysis tool that visualizes source code complexity, generating HTML reports with cyclomatic complexity, Halstead metrics, and lint data from JSHint/ESLint. It runs from the command line or as a Node.js library and produces browsable reports for projects.

## Use cases
- visualize javascript code complexity
- generate cyclomatic complexity reports for a js project
- track code quality metrics over time
- lint and analyze javascript source files
- produce html complexity reports for a codebase
- find complex functions in legacy javascript

## When to choose
- you need visual HTML reports of JavaScript complexity metrics
- you want combined linting (JSHint/ESLint) and complexity analysis in one report
- you prefer a simple CLI or programmatic Node.js API

## When to avoid
- you need actively maintained tooling or modern ES2020+ syntax support
- you need TypeScript or non-JavaScript language analysis
- you need CI-integrated quality gates rather than visual reports
