This example renders a bar chart of the top five most trafficked species from a CSV file loaded with `d3.dsv`. It uses D3.js to append an SVG container, define X and Y scales, and bind data to rectangles for the bars. Axes and labels are added with D3’s axis methods, while the chart title and author attribution are appended as SVG text elements. The visualization relies on the d3-fetch and d3-dsv modules for data parsing and asynchronous loading.
