This bar chart visualizes the distribution of taxi vehicle colors from RDW open data, showing counts for white, black, gray, blue, red, and green taxis. The visualization filters the dataset for passenger cars with a taxi indicator, then aggregates records by primary color. Built with D3.js v5, it uses `d3.json` for data loading, `scaleBand` and `scaleLinear` for the axes, and renders bars as SVG rectangles. The chart highlights color preferences among Dutch taxis.
