This interactive pie chart visualizes the top 10 best-selling books, displaying the relative share of sales (in thousands) for each country. Built with D3 v5 and rendered as SVG, it uses the `pie` layout and `arc` generator to create the chart's segments. The visualization includes a custom legend and data labels, with colors mapped via `scaleOrdinal`. The data is fetched from a remote CSV file using D3's `csv` function, and the project imports specific modules like `select`, `arc`, and `format` to handle rendering.
