Chartkick

Generates interactive charts with one line of Ruby, such as `line_chart User.group_by_day(:created_at).count`, eliminating JavaScript boilerplate and simplifying view logic.

Works seamlessly with Chart.js, Google Charts, and Highcharts, allowing developers to switch adapters without changing the Ruby API, as shown in the setup instructions.

Supports async data loading via URLs to improve page load times and prevent server timeouts, enabling efficient handling of large datasets.

Offers rich options for styling, axes, and labels, plus direct access to underlying library configurations through the `library` parameter for fine-tuned control.
