class RatatuiRuby::Widgets::Chart
Plots data points on a Cartesian coordinate system.
Trends and patterns are invisible in raw logs. You need to see the shape of the data to understand the story it tells.
This widget plots X/Y coordinates. It supports multiple datasets, custom axes, and different marker types.
Use it for analytics, scientific data, or monitoring metrics over time.
