{"version":"1.0","type":"rich","title":"Question_1","description":"This example shows population data for 20 countries as a horizontal bar chart. The bars’ lengths encode each country’s population value, with country names on the y-axis and a bottom axis formatted in billions. Built with React and D3 v5, it uses `scaleBand` for the y-axis, `scaleLinear` for the x-axis, and SVG `rect` elements. The CSV data is loaded via `d3.csv`, and tooltips display the formatted population using the D3 `format` API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d921db6b11e4b8583c340c80ca3880a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
