A scatterplot animates daily COVID-19 case counts across Hubei regions, plotting cumulative confirmed cases on a logarithmic x-axis against new daily cases on a logarithmic y-axis. Each circle represents a region, colored distinctly, and transitions smoothly between dates using D3 v5's `transition().duration()` within a `setInterval` loop. The SVG axes are rendered with `d3.axisLeft` and `d3.axisBottom`, with data parsed from `hubeinxt.csv`.
