.NET MAUI Spline Area Chart - Visualize Data Easily

Overview

The .NET MAUI spline area chart is designed for visualizing quantitative data. It is an area chart type that plots a fitted curve through each data point in a series. It is used to represent time-dependent data and show trends in data at equal intervals.
