## What it is
Chartbuilder is a front-end charting application from Quartz for creating simple, beautiful charts in a consistent predefined style by pasting CSV/TSV data and exporting responsive charts or static SVG/PNG. It was rewritten in React.js and powers chart creation on Quartz's Atlas platform.

## Use cases
- create charts from pasted csv data
- export charts as svg or png
- make responsive mobile-friendly charts for news articles
- produce small multiples chart grids
- build charts in a consistent house style
- hosted tool for quick chart making

## When to choose
- you need publication-ready charts in a fixed style without coding
- you want to paste spreadsheet data and export svg/png quickly
- you're a newsroom producing many charts with consistent branding

## When to avoid
- you need data analysis or transformation - it explicitly is not that
- you want a spreadsheet replacement
- you need highly custom or interactive chart types beyond its predefined styles
- you need actively developed software - last release was 2017
