{"version":"1.0","type":"rich","title":"Vis update","description":"This example shows a bar chart of cities by number of P+R locations, and a pie chart of the capacity distribution for the selected city. The bar chart is drawn with SVG using `d3.scaleBand` and `d3.scaleLinear`, with bars colored in `dodgerblue`. Clicking a bar triggers `updatePie`, which filters sample data and calls `drawPie`. The pie chart uses `d3.pie` and `d3.arc`, with slices colored via `d3.schemeTableau10` and labels showing capacities. The code uses D3 v6 and dummy data based on cleaned RDW data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9dfe22f35aa14e3e8485b157547de439?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
