## What it is
ng2-charts is an Angular library providing directives for rendering Chart.js charts reactively in Angular applications. It supports all eight Chart.js chart types (line, bar, radar, pie, polarArea, doughnut, bubble, scatter) with data binding, configuration options, and click/hover events.

## Use cases
- add charts to an Angular dashboard
- render line and bar charts in Angular from Chart.js datasets
- show pie and doughnut charts with reactive data binding in Angular
- handle chart click and hover events in an Angular app
- reduce bundle size by registering only needed Chart.js components
- migrate Chart.js usage into standalone Angular components

## When to choose
- you are building an Angular application and want Chart.js integration with Angular-style data binding
- you need reactive, responsive charts with typed Angular APIs and schematics support

## When to avoid
- you are not using Angular (use Chart.js directly or a React/Vue wrapper)
- you need chart types or features outside what Chart.js provides

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts, ui-components
- domain: data-visualization, frontend, web-development
- platform: cross-platform
- tags: angular, chartjs, typescript, charts, directive, web-server, nodejs
