Car Sales Donut Graph
This donut chart visualizes car sales by brand, showing the proportion of total vehicles sold for each manufacturer. The chart uses a categorical color scale with distinct hues for each brand, displays sales counts directly on larger segments, and includes an interactive legend listing brand names with corresponding color swatches. Built with D3 v7, the visualization loads car sales data from a CSV file and uses `d3.flatRollup`, `d3.pie`, and `d3.arc` to generate the donut geometry. Only brands with sales exceeding 1,000 units display their counts on the chart.
