Encountering a maximum call stack size error is a common issue when implementing d3.layout.partition in Angular

I recently developed an AngularJS directive to generate a D3 sunburst chart, but I'm encountering issues. I'm receiving a maximum call stack error in Chrome and a too much recursion error in Firefox. After some investigation, I found that the problem lies within the d3.layout.partition function. This function is essential for creating sunburst charts and other hierarchical charts in D3.js. Unfortunately, I'm stuck and unsure of how to resolve this issue. Any suggestions or guidance would be greatly appreciated.

Thank you.

Chrome Error:

Firefox Error:

      var partition = d3.layout.partition()
        .children(function(d){ return d.values; })
        .value(function(d) { console.log(d); return d.count; });            

      var root = d3.nest()
            .key(function(k){ return k.key})
            .entries(d);

      root = {key:'All',values:root};

      console.log(partition.nodes(root))

The issue arises when calling partition.nodes(root), resulting in the recursion error.

It's difficult to pinpoint the exact cause of your issue without seeing more code, but I have encountered a similar problem before and was able to resolve it by following these steps:

Try moving your d3 code to the controller instead of the directive.

If you must keep your d3 code in the directive, consider removing the watcher after the initial watch. Here's an example from

var unbindWatcher = $scope.$watch(
    "clickCount",
    function( newClickCount ) {
        console.log( "Watching click count." );
        if ( newClickCount >= 5 ) {
            $scope.isShowingFeedback = true;
            unbindWatcher(); }
       }
  });

Here are the reasons behind these suggestions:

While some tutorials advocate for placing d3 code directly into the directive (as it manipulates the DOM), I personally find it more effective to control d3 code within the controller. I prefer relying on d3 rather than AngularJS for DOM manipulation. However, my experience with AngularJS is still relatively new, so these are just my initial impressions.
