A scatter plot displays the relationship between confirmed and active COVID-19 cases, with each circle representing a data point. The visualization uses React components to render SVG elements, with d3.scaleLinear managing the x and y scales. Axes are generated from array methods like xScale.ticks() and map(), while the data loads through d3.csv with multiplication applied to numeric values. The chart includes axis labels and tooltips showing formatted values using d3.format with SI notation.
