{"version":"1.0","type":"rich","title":"Fork of CV: Bar Chart","description":"This example shows a bar chart of the 30 most populous cities worldwide using React and D3 v7, with population values displayed in millions on the y-axis and city names on the rotated x-axis. The chart renders as SVG and supports interactive selection—clicking a bar highlights it in red. Data loads from a raw GitHub Gist URL and is parsed manually into an array of city-population objects. The visualization builds scales with `d3.scaleBand` and `d3.scaleLinear`, renders axes via `d3.axisBottom` and `d3.axisLeft`, and uses React hooks for container dimensions and state management.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/16256e69eea1405989466fb0d4401c94?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
