WebForms Chart (HTML5) Overview
The ASP.NET AJAX Chart is a control powered by the Kendo UI Data Visualization Chart widget. The control provides a powerful charting mechanism based on SVG when shown in modern browsers like Firefox, Chrome, IE9+, Opera and VML fallback for older browsers like IE8 and below. It was added to the Telerik® UI for ASP.NET AJAX suite in Q2 2012. RadHtmlChart is the successor to RadChart.
