This fork of a multi-line chart visualizes COVID-19 case counts over time, showing a green line with circular points for each date. It uses D3 v7 with an SVG rendering, employing `d3.scaleBand` for the date axis and `d3.scaleLinear` for the case count axis, plus `d3.line` and `d3.axisBottom`/`d3.axisLeft` to generate the chart. Data is loaded from a remote CSV file containing date and case columns, with the line chart displaying a clear trend of rising cases across the period.
