{"version":"1.0","type":"rich","title":"Fork of D3.js Bar Chart","description":"This example shows a bar chart of the 15 most expensive cities by average cost of living index, with a bold title and hover tooltips revealing each city’s exact value. It loads CSV data from a GitHub gist via `d3.csv`, filters and aggregates it with `d3.nest()` and `d3.mean()`, then renders an SVG using `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom`/`d3.axisLeft` for axes. Bars highlight orange on mouseover, with a tooltip appended dynamically to the page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8f53866a86de4f61ae8879fd8164cd7f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
