This example visualizes survey responses about media interactions as a radar chart, rendering a square-shaped plot that displays aggregated data points for different media types. The visualization computes mean scores from CSV data, which is fetched from a remote GitHub repository, converting response categories into numeric values. The D3 v7 code uses `d3.csvParse`, `d3.group`, and `d3.mean` to process and aggregate the data, while the rendering pipeline follows a declarative `select` pattern to build the SVG chart. The visualization lays groundwork for interactive features like legends and hover effects, though current implementation focuses on static display.
