Not Ideal For

Pros & Cons
Pros
Uses bezier curves to create aesthetically pleasing line charts with fluid animations, enhancing visual engagement compared to standard linear charts.
Built-in gestures like pinch-to-zoom, scrolling, and touch support allow dynamic data exploration, with features like switching between weekly, monthly, and yearly scales.
Extensive configuration via BezierChartConfig enables fine-grained control over colors, gradients, axes, indicators, and physics to match any app design.
Supports multiple data series with distinct labels, colors, and styling on the same chart, useful for comparative time-series or numeric data visualization.
Cons
Setting up charts requires verbose Dart code with numerous parameters, as shown in the examples, which can be overwhelming for simple use cases.
Only supports line charts via bezier curves, lacking common types like bar, pie, or scatter plots, which may necessitate additional packages.
With bezier calculations, animations, and interactive gestures, it might not scale well for very large datasets or high-frequency real-time updates.
