This bubble chart visualizes Walmart sales data, plotting total sales against units sold for each item category, with bubble radius scaled proportionally to sales figures. The chart loads a CSV file from a GitHub gist via the Fetch API, parses the data with string manipulation, and renders using Chart.js on an HTML Canvas element. Six semi-transparent color categories distinguish the data points, while the chart's non-responsive configuration keeps dimensions fixed at 900 by 400 pixels.
