Under Custody displays a small dataset of two gender-based population percentages and counts in an HTML table. Built with React and D3 v5, the table supports interactive sorting by clicking column headers, toggling rows between ascending and descending order. Rows and headers are generated dynamically using React components, while D3 handles the underlying data manipulation logic. The table applies custom CSS styling, including hover effects, alternating row colors, and a colored header row, to improve readability. The example demonstrates a straightforward, reusable React table component capable of rendering and sorting simple structured data.
