## What it is
Chartkick is a Ruby gem (with React and JS variants) that lets you create beautiful JavaScript charts with a single line of code in Rails views or React components. It supports Chart.js, Google Charts, and Highcharts as backends and accepts data as hashes, arrays, or URLs.

## Use cases
- add a line chart of users per day in a Rails view
- render a pie chart from grouped ActiveRecord counts
- create column, bar, area, and scatter charts with one line of Ruby
- build admin dashboards with quick charts
- load chart data asynchronously from a URL endpoint
- add charts to a React app with minimal code

## When to choose
- you're building a Rails or Ruby web app and want charts without hand-writing JavaScript
- you want a simple, batteries-included wrapper over Chart.js, Google Charts, or Highcharts
- you need quick charts for admin panels and dashboards
- you want charts fed directly from ActiveRecord group queries

## When to avoid
- you need fine-grained control over chart rendering beyond what the underlying libraries expose
- you're not using Ruby, Rails, or React
- you need server-side rendering of charts to static images
- you need highly custom or exotic chart types not supported by the backends
