## What it is
D3.js is a free, open-source JavaScript library for visualizing data using SVG, Canvas, and HTML. Its low-level, web-standards-based approach provides fine-grained control for building dynamic, data-driven graphics and custom visualizations.

## Use cases
- create interactive charts in the browser
- build custom data visualizations with svg
- render force-directed network graphs
- visualize hierarchical data like trees and treemaps
- draw geographic maps with map projections
- build a custom charting library on top of low-level primitives

## When to choose
- you need full control over every visual detail of a chart
- you are building bespoke or award-winning data visualizations
- you want a foundation for higher-level charting libraries
- you need specialized visualizations like force layouts, hierarchies, or geo projections

## When to avoid
- you just need standard charts quickly with minimal code
- you prefer a high-level charting API with sensible defaults
- your team cannot invest in learning D3's low-level model

## Facets
- artifact type: library
- maturity: stable
- function: data-visualization, charts, graphics
- domain: data-visualization, frontend, web-development, data-science
- platform: browser
- tags: svg, canvas, d3, charts, dataviz, web-standards, nodejs, javascript
