Starting with R3 2023 (17.2.23.1010) we introduced a new graphics engine implementation, based on the SkiaSharp library, which allows truly cross-platform deployment of Telerik Reporting applications, targeting .NET 6+. This release brings SkiaSharp-based rendering to web report viewers and PDF export format, and the rest are soon to follow. Check GraphicsEngine article section for details.
