## What it is
A declarative charting framework for Angular that renders SVG charts using Angular's rendering engine while leveraging d3 for math, scales, and shape generation. It supports many chart types including bar, line, area, pie, donut, gauge, heatmap, treemap, and Sankey diagrams with customizable CSS styling.

## Use cases
- add charts to an Angular dashboard
- render bar and line charts from data in Angular
- build interactive data visualizations with SVG
- create stacked or grouped bar charts in Angular
- show real-time updating charts
- build a Sankey diagram or treemap in a web app

## When to choose
- you are building an Angular application and need charts
- you want Angular-native rendering with AoT/SSR support instead of a wrapped chart engine
- you need a wide variety of chart types with CSS-customizable styling

## When to avoid
- your project uses React, Vue, or another non-Angular framework
- you need canvas-based rendering for very large datasets
- you need a framework-agnostic charting library

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, charts, ui-components
- domain: data-visualization, frontend, web-development
- platform: cross-platform
- tags: angular, d3, svg, charting, declarative, typescript, web-server, nodejs
