{"version":"1.0","type":"rich","title":"Exploring RDW data - Basic chart with filtering","description":"This example visualizes parking facility capacities from Dutch RDW open data, displaying each location as a bar on a Cartesian chart. A checkbox filters out facilities with unknown capacity, re-scaling the axes and updating the bar positions dynamically. The chart handles the data’s dirty state, where `null` capacities are excluded upon filtering, and it redraws the x-axis tick labels with a rotation for readability. The implementation uses D3 v6 with `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft` to build the SVG, while local JSON test data or a proxied remote API serves as the data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6ed886a5d47c4b839a520af2a8be7488?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
