This visualization presents newly admitted COVID-19 patients in the UK from January 23 to February 2, 2021, as a horizontal bar chart. The React application loads data from a CSV file using d3.csv and renders the chart as SVG elements. D3's `scaleBand` and `scaleLinear` handle the axes, while grid lines and tick labels are generated from `xScale.ticks()`. Each bar's length corresponds to the daily admission count, with the y-axis displaying dates and the x-axis showing admission numbers. The chart is styled with a steelblue fill for the rectangles.
