This line chart displays the cumulative COVID-19 case counts across nine countries over time, with the x-axis representing total cases and the y-axis showing countries. The visualization uses D3 v5 with an SVG canvas, employing `scaleLinear`, `axisBottom`, `axisLeft`, and `line` APIs to render the axis and path. Data is loaded from a remote CSV file via `csv()`, with values parsed and scaled before being drawn as a single red line path.
