XChart

Supports over a dozen chart types including line, scatter, bar, pie, OHLC, and heatmaps, with dedicated builders and stylers for each, as shown in the features table and examples.

Enables dynamic charts with straightforward API calls like updateXYSeries and panel repaint, demonstrated in the real-time example with sine wave generation and SwingUtilities.

All styling options are consolidated in Styler classes and series setters, allowing quick customization without hunting through disparate methods, as illustrated in the chart and series customization sections.

Has no mandatory external dependencies, making it easy to integrate into Java projects with minimal overhead, emphasized in the features list and Maven setup instructions.
