 # Visualize-JSON-Data-Quickly-Using-WPF-Chart
 
+JSON is one of the most widely used data formats, but working with it can be challenging.
+
+This article focuses on extracting data from JSON files and visualizing it using bar charts, line charts, and pie charts from the Syncfusion WPF Charts control.
+
 Four easy steps can be used to quickly display data from a JSON web service using the WPF Charts simplicity:
 1.	Retrieve the data from json string or web service using HttpClient.
 2.	Deserialize the JSON data to create a list of ExpandoObject.
 3.	List of ExpandoObjects to DataTable Conversion
 4.	Set the ItemsSource property of the chart to the data table along with the binding path of the X and Y in the Chart Series.
