This example presents a bar chart of National Park visitor numbers for 2023, sourced from a remote CSV file. The visualization summarizes the data file’s size, row count, and column count in a text box, then sorts parks by visitor totals for the chart. Using D3 v7, it fetches the data, parses it with `d3.csvParse`, scales axes with `scaleBand` and `scaleLinear`, and renders the bars and axes as SVG elements.
