This visualization shows car model sales data for a month in a donut chart. The chart displays sales totals for each car model as proportional arc segments, with labels and tooltips showing sales figures. Built using D3.js v2 and jQuery, the code loads data from a CSV file and uses `d3.layout.pie` and `d3.svg.arc` to generate the donut shape. Animated color fills and a clickable legend with rectangles and text labels enhance interactivity within a React framework, rendering as SVG.
