This visualization shows the daily new cases of Covid in Italy as a scatterplot, with each point’s radius scaled proportionally to the number of intensive care patients on that day. The time-based x-axis uses `scaleTime`, while the y-axis and radius use `scaleLinear`. A toggle button in the top-left corner shows or hides a connected path. Data is fetched via `d3.csv` from the Italian government’s continuously updated GitHub repository, and rendered as SVG with axis generators `axisLeft` and `axisBottom`.
