{"version":"1.0","type":"rich","title":"自定义坐标轴","description":"This bar chart displays the 2019 population of global regions, with a custom y-axis and a horizontal bar layout. The chart uses D3 v5’s `scaleBand` and `scaleLinear` to map regions and population values, while `axisBottom` and `axisLeft` render the axes. Population labels are formatted with the `format` function, replacing \"G\" with \"B\" for billions. The data is loaded from an external CSV file, and the visualization is rendered as SVG elements, with gridlines and a title styled via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2275e1dcd77342869e61ef0e8f02f860?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
