Bug report

In a Diagram, if you have a lot of nested data, a "Maximum call stack size exceeded" error is thrown.

Reproduction of the problem

1. Open this example - https://dojo.telerik.com/OcOBaFoq/3

Current behavior

A Maximum call stack size exceeded error is thrown

Expected/desired behavior

No errors should be thrown.

Environment

• Kendo UI version: 2023.3.1010
• Browser: [all]

I disable the zoom on a diagram by setting the zoom property to 0 and it works.

Unfortunately it crashes the pdf export with the following error:

This is a dojo where the issue reproduces: https://dojo.telerik.com/EveCAnAq

I did a quick investigation in the library and the culprit seems to be the first line of the below function. _zoom is either zero or undefined resulting in NAN. 

Bug report

On Zoom Some Connection lines become bolded

Reproduction of the problem
Dojo: https://dojo.telerik.com/uHOdOHOV/4

Zoom the chart randomly

Current behavior

Some Connection lines become bolded

Expected/desired behavior
Connection lines coordination shall be rounded so they render equally

Environment
Kendo UI version: [all]
Browser: [all]

The documentation of the Kendo-UI Diagram widget specifies the following signature of the zoom method (as do the corresponding TS typings):

zoom(zoom: number, point: kendo.dataviz.diagram.Point): void;

However, the JS implementation looks like this:

zoom: function(zoom, options)

where options is an object that may contain a field called "point" of type kendo.dataviz.diagram.Point.

When using zoom as documented, it ignores the specified point. This DOJO demonstrates the behavior.
