This pie chart visualization breaks down the count of infected individuals across nine countries, including India, USA, Spain, Russia, UK, Italy, France, Germany, and China. The chart displays both region labels and the calculated percentage of the total infected population for each slice. Built using D3.js, the code imports the `select`, `arc`, `pie`, `scaleOrdinal`, and `schemeCategory10` functions from the `d3` module to generate the SVG rendering. The implementation includes a color-coded legend positioned to the right of the chart, with each entry showing the region name and its corresponding infected count.
