This example visualizes parking facility capacities from the Dutch RDW dataset, focusing on the first ten facilities and their associated usage types. It renders a static bar chart using SVG, where each bar represents a facility, and the bar height corresponds to its capacity. Facilities with missing capacity data appear as zero-height bars. The visualization is built with D3 v6, employs `d3.scaleBand` and `d3.scaleLinear` for the axes, and uses `d3.axisBottom` and `d3.axisLeft` to draw the chart's axes. The code includes a data preparation pipeline that selects a subset of the remote data, transforms it, and handles missing values, with a toggle for loading local test data.
