This visualization shows the presence or absence of various genetic markers, including antibiotic resistance genes, across multiple bacterial isolates. A parallel sets diagram displays the data as interconnected vertical columns representing different genes, with flows between them indicating co-occurrence patterns. The code uses D3.js version 6 to render the visualization as an SVG, reading the dataset from a CSV file. Each isolate is a row in the data, and the diagram reveals how genetic markers cluster together across the sample population, though the README incorrectly references world population data.
