The attempt to retrieve a JSON file using the D3 Framework resulted in a 404 Error

I am currently learning the D3 Framework, and I'm facing an issue with loading my Json file. Despite running the script on a server and having the JSON file in the same directory as the html/d3 file, I keep getting a 404 error when checking the console.

The setup is on www.mywebsite.com, and the Json file is stored in www.mywebsite.com/mydata.json. Can anyone provide assistance?

<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script> 
</head>
<body>
    <script type="text/javascript">

    d3.json("mydata.json", function(data){ 

        var canvas= d3.select("body").append("svg")
        .attr("width",500)
        .attr("height", 500)

        canvas.selectAll("rect")
            .data(data)
            .enter()
                .append("rect")
                .attr("width", function(d){ return d.age *10;})
                .attr("height", 50)
                .attr("y", function(d ,i){ return i* 50; })
                .attr("fill", "blue");
    });

    </script>

Check out some potential pitfalls in this source and also in this post. Let us know if you were able to access the json file afterward.

Answer №2

To maintain the current formats, all you need to do is adjust some settings on the server. In my case, I am using an IIS server and encountered a 404 error with JSON files. After making a few modifications, everything was resolved smoothly. If you are also working with an IIS Server, simply follow these steps...

Step 1: Navigate to MIME Types in IIs Server settings.

Step 2: Add the JSON extension from the right-hand side and then restart the server.
