What's new in Swift Charts?

In the latest release of Swift Charts, several new features have been introduced to enhance data visualization capabilities. Here are the key updates:

1. Function Plots:

   • Single Function Line Plot: Allows for visualizing a single mathematical function.
   • Area Plot: Fills the area between two functions, making it easier to visualize the space under a curve or between curves.
   • Parametric Functions: Supports plotting parametric functions where x and y are defined in terms of a third variable, t.
   • Piecewise Functions: Handles piecewise functions, including cases where certain values in the domain do not have an output.

2. Vectorized Plotting APIs:

   • Efficiency: Supports visualizing larger datasets more efficiently by reducing the number of style alternations and computations during rendering.
   • Customization: Allows for skipping certain style customizations for larger datasets to improve performance.

3. Accessibility:

   • VoiceOver Support: Ensures that charts are accessible by default, with VoiceOver describing the chart elements.

4. Customization:

   • Modifiers: Similar to SwiftUI, modifiers can be used to customize the appearance of function plots, such as changing colors and filling areas under curves.
