This visualization displays laptop sales as a pie chart, with each slice representing the total quantity sold per company. It uses D3.js version 3, specifically leveraging the `pie` and `arc` generators to compute slice geometry, and `scaleOrdinal` with `schemeCategory10` to assign colors. The data is loaded from a remote CSV file via D3's `csv` function, then aggregated by company before rendering. The chart is drawn as an SVG element, centered within a 600x450 pixel canvas, with a 150-pixel radius for the pie.
