This interactive dashboard visualizes the distribution of P+R parking capacities across Dutch cities, using data from the RDW open data portal. A bar chart shows the number of P+R locations per city, and clicking any bar generates a pie chart breaking down the parking capacity of each facility within that city. The visualization uses d3.scaleBand and d3.scaleLinear for the bar chart, while the pie chart is built with d3.arc and d3.pie. All graphics are rendered as SVG, with React managing the page structure.
