This example presents a comparative genome browser for multiple phage genomes, displaying genes as colored rectangles along horizontal genome-length rulers. Genes are positioned by their start and stop coordinates, with forward and reverse directions placed on opposite sides of the ruler, and each genome is stacked vertically for comparison. The visualization uses D3.js to load JSON data and render SVG elements, including animated tick marks at 100, 500, and 1000 base-pair intervals, along with tooltip interactions. All visual elements transition smoothly into view using D3 transitions, with gene labels and ruler annotations provided via SVG text.
