{"version":"1.0","type":"rich","title":"D3.js Bar Chart","description":"This bar chart visualizes the 15 most expensive cities by their mean cost of living index, using data filtered from a CSV file loaded via `d3.csv`. Each bar represents a city, with values aggregated through `d3.nest()` and `d3.mean`, and rendered as an SVG via `d3.scaleBand` and `d3.scaleLinear`. Interactive tooltips appear on mouseover, driven by D3 v4 event handlers. The chart includes rotated x-axis labels and a bold title, with bars colored steelblue by default and highlighted orange on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c4c1286c2d34f388a5d08e0f2e49d3b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
