{"version":"1.0","type":"rich","title":"Bar Chart Example","description":"This example displays a bar chart of country populations, with each bar’s width fixed at 300 and height at 400 pixels. The chart is rendered as SVG elements using D3 v6, drawing rectangles via `svg.selectAll('rect').data(data).enter().append('rect')`. Population values are loaded from a CSV file using `d3.csv` and converted to numbers by multiplying by 1000. The current code only appends the rectangles without encoding data into visual attributes, leaving the bars uniform rather than proportional to population.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ebee8d15a3394be3a0f55701d606ca2b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
