Exploring RDW data - Basic chart
The visualization displays parking facility data from the RDW open dataset, plotting variables from a selectable form. It fetches a list of facilities, retrieves static details for the first ten, and logs unique values for fields like limited access. The code uses d3.json with a CORS proxy and d3 v6, rendering an SVG scaffold with margins and a group element, though no axes or bars are drawn yet.
