This pie chart displays total sales by item category, using data fetched from a Walmart CSV file hosted on GitHub. The visualization breaks down sales proportions across categories, with each slice representing a category’s contribution. It loads the data via the Fetch API, parses the CSV text, and passes the category labels and total sales values to Chart.js. The chart is rendered on an HTML canvas element with a fixed 400x400 size, using a semi-transparent color palette for each slice. The code explicitly sets the chart type to `pie` and disables responsive resizing.
