{"version":"1.0","type":"rich","title":"nikhil_D3.js Bar Chart","description":"This example visualizes the top 15 most expensive cities by their mean Cost of Living Index using a bar chart. The code loads CSV data via `d3.csv`, filters by rank, and aggregates values with `d3.nest()` and `d3.mean`. It renders an SVG with `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, using `d3.axisBottom` and `d3.axisLeft`. Bars change color on mouseover and display a tooltip with city and index details.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a6061078585b442eb8afe5d4c25d6ba2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
