This pie chart visualizes total sales across six product categories, with each slice representing a category’s contribution to overall revenue. The chart is rendered on an HTML canvas element using Chart.js, which fetches CSV data from a remote GitHub gist. The code parses the file, extracting item categories and total sales values, then applies semi-transparent background colors and a border width to each slice. The chart is non-responsive, with a fixed 400×400 canvas size, and includes a title displayed above the visualization.
