Power BI Custom Visual D3.js problem

[bhavesh-jadav]

I am trying to create tree structure in Power BI uing [email protected]. But I am having some issue with it. I have a simple update function as shown below.

public update(options: VisualUpdateOptions) {

     console.log("hello1");

     var tree = d3.layout.tree()
	    .size([400, 400]);

     console.log("hello2");
}

As you can see in above code, I am priting hello1 to console then creating tree object using d3 then printing hello2 to finish off. The problem is that I can see the hello1 on the console but I can not see hello2 no matter how many time I refresh the visual. See screenshot of console below.

 

Can someone please tell me why I can not see hello2 into the console?

There's a JavaScript exception. Our recommendation is to wrap update into try-catch to figure out a root of this issue.

public update(options: VisualUpdateOptions) {

     console.log("hello1");

     try {
         var tree = d3.layout.tree()
	       .size([400, 400]);
     } catch(e) {
          console.log(e);
     }

     console.log("hello2");
}
