Cars Report
This example shows a minimalist, abstract car navigation report rendered as a yellow circular canvas with a white horizontal road and a red central hub. A blue directional line rotates from the center to illustrate a single path segment, while the title displays a scaled value. The code uses D3 v7 selections and scales, including `scaleLinear` for the y-axis and `scaleOrdinal` to map direction codes (like ’D5’) to rotation angles. It draws SVG elements—circle, line, and groups—with explicit attributes and transforms, demonstrating basic coordinate and rotation logic.
