This pie chart displays vehicle registration counts by type, using color-coded sections with value labels and a legend that pairs each category with its numeric count. The chart is rendered as an SVG using D3 v5, loading data from a CSV file via the `d3.csv` function. The visualization employs D3's `pie`, `arc`, and `scaleOrdinal` APIs to generate the sectors and colors, while the legend and labels are built using D3's `select` and `append` methods. The styling is defined in a separate CSS file, and the code demonstrates the use of ES6 modules for data fetching and rendering.
