This bar chart displays the number of households on local authority housing waiting lists across nine English regions for 2019, sourced from data.london.gov.uk. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear` for the x-axis and `scaleBand` for the categorical y-axis. Bars are drawn as SVG rectangles, with axes generated via `axisLeft` and `axisBottom`. The chart includes a title and x-axis label, with a grey gridline via `tickSize` on the bottom axis.
