{"version":"1.0","type":"rich","title":"柱状图","description":"This bar chart displays population estimates for six global regions in 2019, with horizontal bars ordered by region name. The visualization uses D3 v5 with SVG rendering, leveraging `scaleLinear` for the population axis and `scaleBand` for categorical region placement. Data is loaded from a CSV file via `d3.csv`, and population values are multiplied by 1000 before mapping to bar widths. Axes are generated with `axisLeft` and `axisBottom`, while rectangles represent each region’s population, styled with steelblue fill.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/69b575c0ab3542eebc929c56fa94537c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
