{"version":"1.0","type":"rich","title":"Let's make a bar chart","description":"A bar chart displays population values for East African nations from a CSV file, with repeated entries producing overlapping rectangles. Each data point becomes a square via D3's `selectAll`, `data`, and `enter` methods, set to fixed 300-pixel dimensions. The code loads the data using `d3.csv`, multiplies population values by 100, and renders SVG rectangles without axis or scaling logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e69f4ce838e34caf9adbf4c092249133?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
