Utilizing D3 to load XML data from a file and implementing scales for a bar chart

I came across a helpful tutorial on d3 that focuses on creating a bar chart using scales. Unfortunately, I encountered an issue while trying to load my data from an XML file. It seems like my problem lies in not properly determining the length of the dataset when creating xScale and yScale variables.

Below is the sample XML file:

<data>
<value>5</value>
<value>10</value>
... // Remaining dataset values here
</data>

Here is the code snippet for reference:

<!DOCTYPE html>
<html lang="en">
// Code block starts here

It's a common error. Instead of using "d", make sure to use "d.value". Your sample data consists of an array of numbers, whereas your JSON data comprises an array of objects with a "value" attribute.

To visualize the difference, try running this example:

http://jsfiddle.net/5edkw/1/

As embedding jsfiddle links requires code snippet, here is a reminder for you:

 .attr("height", function(d) {
    return yScale(d.value);
 })

The "/0/" version corresponds to the original one you shared on pastebin.
