It would be nice if the diagram control could have undo/redo event.

It would love to have an export feature for Diagram which will give the possibilty to make an export to Microsoft Visio.

It should be allowed to extend the Diagram plot area to more than 20000px and/or to calculate the max scroll width based on the Diagram content.

Automatic Layout and Data Source in case of non-TreeView data

In the diagram control automatic layout and data source works just for a tree view. For example in a non tree view data we would have several levels with items that can have multiple parents. In this case I have to create the items in the diagram manually...it would be nice to update this behaviour and to be able to use the diagram with automatic data source and layout also in the case of a non TreeView data.

It will be nice to create shapes with rounded borders

Add built-in support for guidelines that will be visible as an infinite grid of lines, with a snap-to capability.

Its good to have minimize and maximize the shapes drawn with kendo diagram as seen in this example
https://gojs.net/latest/samples/IVRtree.html

it will very useful when we are drawing with a huge data. we can clearly see the actual flow as required

It would be nice if, in addition to "polyline" and "cascading", if there were other options for the shape of the diagram connectors.  I would like to see a "spline" option that possibly follows a similar path to the "cascading" square shape, but flows with curves.   Maybe even a configuration object, instead of a string that could define the parameters of the shape.

{ 
type: "spline", 
mode: "bezier", // or "natual" or any other spline algorithm //
maxCurves: 3, // max number of inversion points in the spline //
curveRadius: 100 // size in pixels //
// any additional properties for configuring the curve, like bezier length, instead of curve radius &c. //
}

Problem:
Currently when a Rectangle together with a large TextBlock is contained by a Shape where the Rectangle should enclose the TextBlock it is not resized by the size of the TextBlock, but the TextBlock is overflowing the Rectangle.

Possible solution:
Make the Rectangle a "visual group" so child elements like e.g. TextBlock or Image can be added to it and it will resize with the size of it's children.

Please can you add support for Venn diagrams with drop and drop support for data items to allow dynamic generation.

Fish Bone diagram is a nice feature which is very useful for the applications to provide the root cause analysis in any vertical.

Syncfusion is having a nice in built control to do the same.

A similar feature from Kendo UI is needed to include it in our existing applications.

Hi, 

Your documentation mentions the rotation-thumb and also allows for some styling:

https://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/diagram/configuration/editable.rotate

The only problem is, I cannot get it to display.

See: https://jsfiddle.net/6qmgj521/

Beware: I do NOT mean the 90 degree rotation buttons in the toolbar, but the rotation-thumb adorner!

I expect to see:

Kind regards,

The data item is available to the event arguments of the function handler for shapeDefaults.content.visual function but it is not available to connectionDefaults.content.visual Function. Here is an example illustrating the issue: https://dojo.telerik.com/EMAzeruG

Can it be added?
