{"version":"1.0","type":"rich","title":"Making a Bar Chart","description":"This example builds a bar chart of country populations from a CSV file. It uses D3 v5 methods such as `d3.csv`, `scaleLinear`, and `scaleBand` to map population values to screen coordinates, while `select` and `data` joins append SVG rectangles for each country. The chart renders with a 960-by-500 SVG canvas, and the code includes placeholder ranges and dimensions that are not fully implemented.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5d04246f75ec40f291d8ec12dd011f5b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
