I'm using a diagram in ASP.Net MVC that is very similar to the example here. However, I need the ability to change the content in the shapes depending on options selected on the screen. So, for example, I have a checkbox on the screen that will turn the pictures on or off. The same could be done with, for example, the name or position. Is there any way that this could be done?

Hello Geoff,

You can dynamically trigger a redraw of the Diagram shapes and using if-statements in the shape visual function to determine whether or not to display some of the shape content:
function visualTemplate(options) {
  var dataviz = kendo.dataviz;
  var g = new dataviz.diagram.Group();
  var dataItem = options.dataItem;
 
  if(showImages){
    g.append(new dataviz.diagram.Image({
      x: 3,
      y: 3,
      width: 68,
      height: 68
    }));
  }
  // ............

You can see a sample here: http://dojo.telerik.com/@tsveti/ukUtu/4.

You can also take a look at this article in the documentation, which elaborates on a similar scenario.
