 JSON data cannot be bound directly to the [SfCartesianChart](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.Charts.SfCartesianChart.html?tabs=tabid-1), so you should deserialize the JSON data to a bindable format. Use the open-source NuGet [Newtonsoft.Json](https://www.nuget.org/packages/Newtonsoft.Json/) to serialize and deserialize the JSON objects.
 
+## Overview
+
+Syncfusion’s SfCartesianChart in .NET MAUI supports binding to a variety of data sources, including JSON arrays. This allows developers to dynamically load chart data from web APIs, local files, or embedded resources using deserialized JSON objects.
+
+## Use cases
+
+- Dynamic Data Loading: Load chart data from REST APIs that return JSON.
+- Offline Visualization: Bind charts to locally stored JSON files for offline scenarios.
+- Data Transformation: Preprocess JSON data before binding to customize chart behavior.
+- Cross-Platform Sharing: Use JSON as a portable format to share chart data across platforms.
+- Real-Time Dashboards: Update chart data dynamically by parsing live JSON feeds.
+
 The following steps explain how to pass JSON data to the [SfCartesianChart](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.Charts.SfCartesianChart.html?tabs=tabid-1).
