{"version":"1.0","type":"rich","title":"Making a bar chart","description":"A bar chart displays population figures for nine countries, with steel-blue rectangles whose lengths encode each nation’s population. The chart uses D3 v5’s `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft`/`axisBottom` to render ticks. Data loads from a CSV via `d3.csv`, and the SVG renders axis groups and rectangles through `append` and `enter` selections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9dc1bdeca064479b833ac4e474f92cbd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
