This visualization presents a pie chart of the top 10 most frequent math scores from a dataset loaded via `d3.csv`. It shows the distribution of these scores by count, with a legend displaying each score and its frequency. The code uses `d3.pie()` and `d3.arc()` to generate the SVG slices, with `d3.schemeCategory10` providing a custom color palette. The chart is rendered with `d3.v7` in an HTML page, fetching data from a GitHub gist URL.
