This visualization displays the Dasuttara Sutta (DN 34) as a color-coded heatmap-style grid, mapping 34 groups of teachings across ten numerical categories (ones through tens). Built with React and D3 v7, it uses `ResizeObserver` to track container dimensions and renders an SVG grid via `selection.join()`. Each cell uses `d3.select` to create rect elements with color derived from category position, while `append('title')` provides hover tooltips containing sutta content.
