A horizontal bar chart displays population counts across weekly periods from 2019-W31 to 2019-W35. The bars are drawn as green SVG rectangles using D3 v5’s `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis, with `axisLeft` and `axisBottom` providing tick labels. Data is loaded from a local CSV file via `d3.csv`, and numeric values are coerced with unary plus. The visualization uses an SVG container with fixed margins, rendering the chart in a clean, minimal style.
