This visualization displays the progression of confirmed COVID-19 cases over time as a single orange line chart. The x-axis maps dates using `d3.scaleTime`, while the y-axis uses `d3.scaleLinear` to represent case counts. Data is loaded via `d3.csv` from a GitHub gist and parsed with `d3.timeParse`. The line is rendered with `d3.line`, and axes are drawn using `d3.axisBottom` and `d3.axisLeft`. The SVG structure is built with D3 v6, with explicit margins, axis labels, and a white background.
