## What it is
A TypeScript library for creating animated data visualization videos, rendering charts like bar chart races, line, pie, and map charts via the Canvas API. It exports videos directly frame-by-frame, optionally using FFmpeg (wasm or local) instead of screen recording.

## Use cases
- create animated bar chart race videos from data
- generate data visualization animation videos without screen recording
- render charts to video at any resolution and frame rate
- make animated intro/outro video segments from datasets
- export transparent-background chart animations
- programmatically build custom animated chart components

## When to choose
- you want to turn ranked time-series data into polished animation videos
- you need deterministic frame-by-frame video export with stable FPS
- you want a programmable Canvas-based charting animation library
- you need transparent background or arbitrary resolution output

## When to avoid
- you need a no-code GUI tool - it requires reading source and writing TypeScript
- you need static charts or interactive dashboards rather than rendered video
- you need a maintained, actively developed project - releases stopped in 2023
- you need server-side charting for web apps rather than video output

## Facets
- artifact type: library
- maturity: maintenance
