This horizontal bar chart displays the population of New York City’s five boroughs, with bars ordered from Bronx to Staten Island. It uses D3 v5’s `scaleLinear` and `scaleBand` to map population values and borough names, rendering SVG rectangles scaled by population. Axes are drawn with `axisBottom` and `axisLeft`, with tick labels formatted using D3’s `format('.3s')` to abbreviate millions. Data is loaded via `csv` from a local data.csv file, and populations are multiplied by 1000 before rendering.
