This example visualizes customer data from a CSV file as a pie chart, showing the distribution of values in the sixth column across categories in the fourth column. It uses the Chart.js library to render the chart on an HTML canvas element, with data fetched from a GitHub Gist URL. The chart displays up to ten color-coded slices, and the rendering approach relies on Chart.js’s pie chart type with a fixed canvas size of 400 by 400 pixels.
