{"version":"1.0","type":"rich","title":"Making a Bar Chart","description":"A bar chart displays population estimates for ten countries, with each bar’s height proportional to values from a CSV file. The visualization loads data via `d3.csv`, converts population strings to numbers using unary plus, then renders SVG rectangles scaled to the chart’s height and width attributes. Styling is handled by a linked stylesheet, while the chart itself is built with D3 v7’s `select` and `csv` methods, drawing directly into the static SVG container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ecd4cbe675c447baa595a07939f68cc4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
