This visualization shows the relationship between Country/Region and Confirmed COVID-19 cases for the first 15 entries in a dataset, rendered as a horizontal bar chart using React and D3 v5. The code uses `d3.csv` to load data, `scaleBand` for the categorical y-axis, and `scaleLinear` for the numeric x-axis. SVG rectangles represent the bars, with red gridlines and text labels drawn via D3 selections. The chart is embedded in a React component with a blue title, and data originates from a GitHub gist URL.
