This example displays the progression of confirmed COVID-19 cases over time as a line chart. It uses D3.js v6 (d3.csv, d3.scaleTime, d3.scaleLinear, d3.line, d3.axisBottom, d3.axisLeft) and is rendered as an SVG within a React-based HTML page. The data is loaded from a GitHub-hosted CSV file, with dates parsed using d3.timeParse. The chart includes labeled axes, a tooltip, and a styled orange line, all set against a white background.
