Thanks for your interest in Aspose.Slides. I have observed your requirements and like to share that Aspose.Slides can only import HTML text to presentation slide text frame. There is no option to import charts inside presentation as Aspose.Slides only support MSO charts. You can write your own routine in this regard to read the Kendo UI charts and make similar charts using Aspose.Slides. Please share, if I may help you further in this regard.
