Using an external JSON file to populate a D3 chart

My D3 chart is currently displaying data from the same HTML page. However, I need to switch to using an external JSON file for populating the chart with data generated from a form. When attempting to replace the current "hard coded" data with the d3.json function, the chart gets completely destroyed. Can anyone help me figure out where I am going wrong?

Current files:

<script>
        // Existing code here...
    </script>

I want to replace the current data with this external JSON file:

[
      [
        {
            "key": "ING_SW_CB",
            "value": "5"
        },
        {
            "key": "SB_SW_CB",
            "value": "5"
        },
        // Other data points...
      ]
    ]

Your assistance in getting this resolved quickly is greatly appreciated as I have a deadline to meet!
