This visualization displays the COVID-19 infection rates across various regions and countries. Using a bar chart rendered via SVG, it maps each geographic area to a proportional bar height, with the y-axis representing the infection rate as a fraction. The code employs d3.scaleBand and d3.scaleLinear to position the bars and scales the data, while d3.axisBottom and d3.axisLeft generate the labeled axes. Hovering over a bar changes its color to orange, providing an interactive highlight. The dataset is embedded directly in the script as an array of objects.
