Charts - Overview

DevExtreme ASP.NET Core Charts are jQuery-based components for creating dynamic charts. Transform data into visually appealing charts, including line, bar, pie, treemap, bubble, polar, radar, and more. You can configure each chart with Razor C# syntax for use in MVC views and Razor Pages.
